General Description

PRODUCT HIGHLIGHTS AVDD AGND REF REFGND 16-Bit, 100 kSPS, Differential ADC AD7675* FUNCTIONAL BLOCK DIAGRAM DVDD DGND OVDD AD7675 IN+ IN– SERIAL PORT SWITCHED CAP DAC 16 OGND SER/PAR BUSY DATA[15:0] CLOCK PD RESET PARALLEL INTERFACE CS RD OB/2C BYTESWAP CONTROL LOGIC AND CALIBRATION CIRCUITRY CNVST The AD7675 is a 16-bit, 100 kSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 5 V power supply.

The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7675 is hardware factory calibrated and is comprehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity.
