The AD5307/AD5317/AD53271 are quad 8-,10-,12-bit buffered
voltage-output DACs in 16-lead TSSOP that operate from single
2.5 V to 5.5 V supplies and consume 400 μA at 3 V. Their on-
chip output amplifiers allow the outputs to swing rail-to-rail with
a slew rate of 0.7 V/μs. The AD5307/AD5317/AD5327 utilize
Low power operation: 400 μA @ 3 V, 500 μA @ 5 V
versatile 3-wire serial interfaces that operate at clock rates up to
2.5 V to 5.5 V power supply
30 MHz; these parts are compatible with standard SPI, QSPI,
Guaranteed monotonic by design over all codes
Power down to 90 nA @ 3 V, 300 nA @ 5 V (LDAC pin)
Double-buffered input logic
Buffered/unbuffered reference input options
MICROWIRE, and DSP interface standards.
The references for the four DACs are derived from two reference
pins (one per DAC pair). These reference inputs can be configured
Output range: 0 V to VREF or 0 V to 2 VREF
Power-on reset to 0 V
as buffered or unbuffered inputs. Each part incorporates a power-
on reset circuit, ensuring that the DAC outputs power up to 0 V
Simultaneous update of outputs (LDAC pin)
and remain there until a valid write to the device takes place.
Asynchronous clear facility (CLR pin)
There is also an asynchronous active low CLR pin that clears all
Low power, SPI®-, QSPI™-, MICROWIRE™-, and DSP-
compatible 3-wire serial interface
SDO daisy-chaining option
On-chip rail-to-rail output buffer amplifiers
Temperature range of −40°C to +105°C
Portable battery-powered instruments
DACs to 0 V. The outputs of all DACs can be updated simul-
taneously using the asynchronous LDAC input. Each part
contains a power-down feature that reduces the current
consumption of the device to 300 nA @ 5 V (90 nA @ 3 V). The
parts can also be used in daisy-chaining applications using the
Digital gain and offset adjustment
