Specified for operation of 1.8 V to 5 V, they can be used in portable applications that are powered from a single-cell Li-ion or two-cell batteries. They have rail-to-rail input and output capability for maximum signal swings in low-voltage applications. The LMV98x input common-mode voltage extends 200 mV beyond the rails for increased flexibility. The output can swing rail-to-rail unloaded and typically can reach 80 mV from the rails, while driving a 600-Ω load (at 1.8-V operation).

Pulling the SHDN pin low puts the amplifiers in shutdown, where only 0.156 mA typically is consumed from a 1.8-V supply. In normal operation with the same 1.8-V supply, the devices typically consume a quiescent current of 103 mA per channel, and yet they are able to achieve excellent electrical specifications, such as 101-dB open-loop DC gain and 1.4-MHz-gain bandwidth. Furthermore, the amplifiers offer good output drive characteristics, with the ability to drive a 600-Ω load and 1000-pF capacitance, with minimal ringing. The LMV981 and LMV982 devices are offered in the latest packaging technology to meet the most demanding space-constraint applications. The LMV981 is offered in standard SOT-23 and SC-70 packages. The LMV982 is available in the 10-pin MSOP package. The LMV98x devices are characterized for operation from −40°C to 125°C, making them universally suited for commercial, industrial, and automotive applications. simplified schematic VCC+ IP VBIAS1 I1 I2 M5 M6 M1 M2 Q1 IN− Class AB Control Q4 Q3 Q2 IN+ OUT M3 M4 M7 M8 IN VBIAS2 I3 I4 VCC− 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 LMV981 SINGLE, LMV982 DUAL 1.8 V OPERATIONAL AMPLIFIERS WITH RAIL TO RAIL INPUT AND OUTPUT AND SHUTDOWN SLOS440G − AUGUST 2004 − REVISED MAY 2005 absolute maximum ratings over free-air temperature range (unless otherwise noted)† Supply voltage, VCC+ − VCC− (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5.5 V Differential input voltage, VID (see Note 2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values (except differential voltages and VCC specified for the measurement of IOS) are with respect to the network GND. 2. Differential voltages are at IN+ with respect to IN−. 3. Applies to both single-supply and split-supply operation. Continuous short-circuit operation at elevated ambient temperature can result in exceeding the maximum-allowed junction temperature of 150°C. Output currents in excess of 45 mA over long term may adversely affect reliability. 4. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 5. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions MIN VCC TA Supply voltage (VCC+ − VCC−) Operating free-air temperature 1.8 −40 MAX 5 125 UNIT V °C ESD protection TEST CONDITIONS Human-Body Model Machine Model TYP 2000 200 UNIT V V POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3 SLOS440G − AUGUST 2004 − REVISED MAY 2005 LMV981 SINGLE, LMV982 DUAL 1.8 V OPERATIONAL AMPLIFIERS WITH RAIL TO RAIL INPUT AND OUTPUT AND SHUTDOWN electrical characteristics at TA = 25°C, VCC+ = 1.8 V, VCC− = 0 V, VIC = VCC+/2, VO = VCC+/2, RL > 1 MΩ, and SHDN tied to VCC+ (unless otherwise noted) PARAMETER TEST CONDITIONS LMV981 (single) VIO Input offset voltage LMV982 (dual) TA 25°C Full range 25°C Full range 25°C VIC = VCC+ − 0.8 V IIB Input bias current 25°C 25°C Full range 25°C IIO Input offset current Full range 25°C Full range ICC Supply current (per channel) In shutdown LM982 0 ≤ VIC ≤ 0.6 V, 1.4 V ≤ VIC ≤ 1.8 V CMRR Common-mode rejection ratio 0.2 V ≤ VIC ≤ 0.6 V, 1.4 V ≤ VIC ≤ 1.6 V −0.2 V ≤ VIC ≤ 0 V, 1.8 V ≤ VIC ≤ 2 V kSVR Supply-voltage rejection ratio Common-mode input voltage range 1.8 V ≤ VCC+ ≤ 5 V 25°C LMV981 Full range 25°C Full range 25°C −40°C to 85°C −40°C to 125°C 25°C 25°C Full range 25°C VICR CMRR ≥ 50 dB RL = 600 Ω to 0.9 V, VO = 0.2 V to 1.6 V, VIC = 0.5 V RL = 2 kΩ to 0.9 V, VO = 0.2 V to 1.6 V, VIC = 0.5 V RL = 600 Ω to 0.9 V, VO = 0.2 V to 1.6 V, VIC = 0.5 V RL = 2 kΩ to 0.9 V, VO = 0.2 V to 1.6 V, VIC = 0.5 V −40°C to 85°C −40°C to 125°C 25°C Full range 25°C Full range 25°C Full range 25°C Full range 60 55 55 50 75 70 VCC− − 0.2 VCC− VCC− + 0.2 77 73 80 75 dB 75 72 78 75 100 90 105 101 −0.2 to 2.1 VCC+ + 0.2 VCC+ VCC+ − 0.2 72 100 dB dB 78 0.178 0.156 103 13 5.5 15 35 65 75 25 40 185 205 1 2 3.5 5 mA A nA nA 1 MIN TYP 1 MAX 4 6 5.5 7.5 mV/°C mV UNIT aV IO Average temperature coefficient of input offset voltage V LMV981 AV Large-signal voltage gain LMV982 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 LMV981 SINGLE, LMV982 DUAL 1.8 V OPERATIONAL AMPLIFIERS WITH RAIL TO RAIL INPUT AND OUTPUT AND SHUTDOWN SLOS440G − AUGUST 2004 − REVISED MAY 2005 electrical characteristics at TA = 25°C, VCC+ = 1.8 V, VCC− = 0 V, VIC = VCC+/2, VO = VCC+/2, RL > 1 MΩ, and SHDN tied to VCC+ (unless otherwise noted) (continued) PARAMETER TEST CONDITIONS RL = 600 Ω to 0.9 V, VID = ±100 mV 100 VO Output swing High level RL = 2 kΩ to 0.9 V, VID = ±100 mV 100 Low level Sourcing Sinking High level Low level TA 25°C Full range 25°C Full range 25°C Full range 25°C Full range 25°C Full range 25°C Full range 25°C 4 3.3 7 5 19 1.0 0.55 25°C See Note 6 25°C 25°C 25°C f = 1 kHz, VIC = 0.5 V f = 1 kHz f = 1 kHz, AV = 1, RL = 600 Ω, VID = 1 VPP See Note 7 25°C 25°C 25°C 25°C 1.4 0.35 67 7 60 0.06 0.023 123 MHz V/mS deg dB nV/√Hz pA/√Hz % dB ms 9 mA 8 1.75 1.74 0.024 0.035 0.04 1.77 MIN 1.65 1.63 0.077 0.105 0.12 V TYP 1.72 MAX UNIT IOS Output short-circuit current VO = 0 V, VID = 100 mV VO = 1.8 V, VID = −100 mV Ton Turn-on time from shutdown Turn-on
