AD7934BRU-REEL
数据手册.pdf4通道， 1.5 MSPS ，具有序10位和12位并行ADC 4-Channel, 1.5 MSPS, 10-Bit and 12-Bit Parallel ADCs with a Sequencer
GENERAL DESCRIPTION
The AD7933/AD7934 are 10-bit and 12-bit, high speed, low power, successive approximation SAR analog-to-digital converters ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1.5 MSPS. The parts contain a low noise, wide bandwidth, differential track and-hold amplifier that handles input frequencies up to 50 MHz.
