The AD7699BCPZRL7 from Analog Devices Inc. is an 8-channel, 16-bit, 500 kSPS PulSAR® ADC with a single supply operation. This adc device is designed for multi-channel,
low-power data acquisition systems and includes a true 16-bit SAR ADC without code loss, an 8-channel multiplexer for input configuration, an internal 4.096V low-drift
reference and buffer, a temperature sensor, an optional single-pole filter, and a sequencer for continuous scanning of channels in sequence. It communicates via a simple
SPI interface and is housed in a 20-pin LFCSP package, suitable for operation in temperatures ranging from -40°C to +85°C 。
AD7699BCPZRL7 Features:
· 16-bit resolution with no loss of code.
· An 8-channel multiplexer with selectable inputs: unipolar single-ended, differential (using reference ground), or pseudo-bipolar.
· Throughput rate of 500 kSPS.
· Integral non-linearity (INL) of ±0.5 LSB typical, maximum ±1.5 LSB (±23 ppm or FSR).
· Dynamic range of 93.3 dB.
· Signal-to-noise and distortion ratio (SINAD) of 91.5 dB at 20 kHz.
· Total harmonic distortion (THD) of -97 dB at 20 kHz.
· Multiple reference source types, including an internal 4.096V reference, an external buffered reference up to 4.096V, and an external reference up to VDD.
· Internal temperature sensor.
· Channel sequencer, optional single-pole filter, and busy indicator.
· No pipeline delay with SAR architecture.
· Single power operation at 5V, with logic interface voltage from 1.8V to 5V.
· Serial interface compatible with SPI, MICROWIRE, QSPI, and DSP.
· Power consumption of 26 mW at 500 kSPS and 5.2 μW at 100 SPS.
· Standby current of 50 nA .
