Data Sheet 4-Channel, 200 kSPS 12-Bit ADC with Sequencer in 16-Lead TSSOP AD7923 FEATURES Fast throughput rate: 200 kSPS Specified for AVDD of 2.7 V to 5.25 V Low power 3.6 mW max at 200 kSPS with 3 V supply 7.5 mW max at 200 kSPS with 5 V supply 4 (single-ended) inputs with sequencer Wide input bandwidth 70 dB Min SNR at 50 kHz input frequency Flexible power/serial clock speed management No pipeline delays High speed serial interface SPI®-/QSPITM-/ MICROWIRETM-/DSP-compatible Shutdown mode: 0.5 μA max 16-lead TSSOP package Qualified for automotive applications GENERAL DESCRIPTION The AD7923 is a 12-bit, high speed, low power, 4-channel, successive approximation (SAR) ADC. It operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 200 kSPS. It contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 8 MHz. The conversion process and data acquisition are controlled by CS and the serial clock, allowin...
