AD7988-1BCPZ-RL7

模数转换器 - ADC 16-Bit 100ksps Ultra Lo Pwr SAR

16-Bit Lower Power  PulSAR ADCs in MSOP/LFCSP

GENERAL DESCRIPTION AD7988-1BCPZ-RL7

The AD7988-1/AD7988-51 are 16-bit, successive approximation, analog-to-digital converters (ADC) that operate from a single power supply, VDD. The AD7988-1 offers a 100 kSPS throughput, and the AD7988-5 offers a 500 kSPS throughput. They are low power, 16-bit sampling ADCs with a versatile serial interface port. On the CNV rising edge, they sample an analog input, IN+, between 0 V to VREF with respect to a ground sense, IN−. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD.
