AD7195BCPZ Description

Short technical summary and product information.

The AD7195BCPZ from Analog Devices is a complete analog front end for high precision measurement applications. It integrates a low noise, 24-bit sigma-delta ADC with a programmable gain amplifier (PGA) and AC excitation for removing DC errors. The device supports output data rates from 4.7 Hz to 4.8 kHz and provides programmable gain from 1 to 128.

 

Key electrical characteristics include an RMS noise of 8.5 nV at 4.7 Hz with gain = 128, up to 22.5 noise-free bits at gain = 1, offset drift of 5 nV/°C, and gain drift of 1 ppm/°C. The ADC operates from analog and digital supply voltages of 4.75 V to 5.25 V and 2.7 V to 5.25 V respectively, with a typical supply current of 6 mA.

 

The AD7195BCPZ features a 3-wire serial SPI interface compatible with QSPI, MICROWIRE, and DSP. It is designed for surface mount assembly in a 32-lead LFCSP (5x5 mm) package and operates over a temperature range of -40°C to +105°C. Typical applications include weigh scales, strain gage transducers, pressure measurement, temperature measurement, chromatography, PLC/DCS analog input modules, data acquisition, and medical instrumentation.
