Data Sheet Dual Pseudo Differential 16-Bit, 1 MSPS PulSAR ADC 12.0 mW in QSOP AD7902 FEATURES GENERAL DESCRIPTION 16-bit resolution with no missing codes The AD7902 is a dual 16-bit, successive approximation, analog- Throughput: 1 MSPS to-digital converter (ADC) that operates from a single power Low power dissipation supply, VDDx, per ADC. It contains two low power, high speed, 7.0 mW at 1 MSPS (VDD1 and VDD2 only) 12.0 mW at 1 MSPS (total) 16-bit sampling ADCs and a versatile serial port interface (SPI). On the CNVx rising edge, the AD7902 samples an analog input, 140 µW at 10 kSPS INL: ±1.0 LSB typical, ±2.5 LSB maximum IN+, in the range of 0 V to VREF with respect to a ground sense, IN−. The externally applied reference voltage of the REFx pins SINAD: 91 dB at 1 kHz THD: −105 dB at 1 kHz Pseudo differential analog input range 0 V to VREF with VREF between 2.4 V to 5.1 V Allows use of any input range Easy to drive with the ADA4841-1/ADA4841-2 No pipeline delay Si.
