The AD7904/AD7914/AD7924 are respectively, 8-bit, 10-bit, and 12-bit, high speed, low power, 4-channel, successive-approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low noise, wide bandwidth track/hold amplifier that can handle input frequencies in excess of 8 MHz..
Fast Throughput Rate: 1 MSPS Specified for VDD of 2.7 V to 5.25 V Low Power: 6 mW max at 1 MSPS with 3 V Supplies 13.5 mW max at 1 MSPS with 5 V Supplies 4 (Single-Ended) Inputs with Sequencer Wide Input Bandwidth: AD7924, 70 dB SNR at 50 kHz Input Frequency Flexible Power/Serial Clock Speed Management No Pipeline Delays High Speed Serial Interface SPITM/QSPITM/ MICROWIRETM/DSP Compatible Shutdown Mode: 0.5 A Max 16-Lead TSSOP Package
4-Channel, 1 MSPS, 8-/10-/12-Bit ADCs with Sequencer in 16-Lead TSSOP AD7904/AD7914/AD7924
