The AD7951BSTZ is a 14-bit, charge redistribution SAR ADC fabricated on Analog Devices' iCMOS high voltage process. It offers a maximum sampling rate of 1 MSPS in warp mode, with 800 kSPS in normal mode and 670 kSPS in impulse mode. The device features a differential input with programmable unipolar/bipolar input ranges of 5 V, 10 V, ±5 V, and ±10 V, selectable via pins or serial SPI interface.
Key electrical characteristics include an integral nonlinearity (INL) of ±0.3 LSB typical and ±1 LSB maximum, and a signal-to-noise ratio (SNR) of 85 dB at 2 kHz. Power dissipation is 10 mW at 100 kSPS and 235 mW at 1 MSPS. The ADC includes an internal 5 V reference with typical drift of 3 ppm/°C, and supports parallel (14- or 8-bit bus) and serial (SPI, QSPI, MICROWIRE, DSP-compatible) data interfaces.
The AD7951BSTZ is designed for applications such as process control, medical instruments, high speed data acquisition, digital signal processing, instrumentation, spectrum analysis, and ATE. It operates over a temperature range of -40°C to +85°C and is available in a 48-lead LQFP (7x7 mm) surface-mount package.
