AD7904BRUZ-REEL7: 4-Channel, 1 MSPS, 8-Bit A/D Converter with Sequencer in 16-Lead TSSOP

AD7904BRUZ-REEL7 简述

The AD7924/AD7914/AD7904 are respectively 12-bit, 10-bit, and 8-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, which can handle input frequencies in excess of 8 MHz.

The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point. There are no pipeline delays associated with the part.

The AD7924/AD7914/AD7904 use advanced design techniques to achieve very low power dissipation at maximum throughput rates. At maximum throughput rates, the AD7924/AD7914/AD7904 consume 1.8 mA with 3 V supplies and, with 5 V supplies, the current consumption is 2.5 mA.

AD7924/AD7914/AD7904分别是12位、10位和8位高速、低功耗、4通道、逐次逼近型ADC,采用2.7 V至5.25 V单电源供电,最高吞吐量达1 MSPS。这些器件内置一个低噪声、宽带宽采样/保持放大器,可处理8 MHz以上的输入频率。

转换过程和数据采集过程通过CS和串行时钟信号进行控制,从而为器件与微处理器或DSP轻松接口创造了条件。输入信号在CS的下降沿进行采样,而转换同时在此处启动。该器件无流水线延迟。

AD7924/AD7914/AD7904采用先进的设计技术,可在最高吞吐量下实现极低的功耗。在最高吞吐量下,采用3 V电源时,AD7924/AD7914/AD7904的功耗为1.8 mA；采用5 V电源时,功耗为2.5 mA。
