AD7366BRUZ-5500RL7: 真双极性输入、12位、双通道、同时采样SAR ADC

The AD7366-5/AD7367-5 are dual, 12-/14-bit, low power, successive approximation analog-to-digital converters (ADCs) that feature throughput rates up to 500 kSPS. Each device contains two ADCs, which are both preceded by a 2-channel multiplexer, and a low noise, wide bandwidth, track-and-hold amplifier.

The AD7366-5/AD7367-5 are fabricated on the Analog Devices, Inc., industrial CMOS process (iCMOS(R))2, which is a technology platform combining the advantages of low and high voltage CMOS. The process allows the parts to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366-5/AD7367-5 can accept true bipolar analog input signals in the ±10 V range, ±5 V range, and 0 V to +10 V range.

The devices have an on-chip 2.5 V reference that can be disabled to allow the use of an external reference. If a 3 V reference is applied to the DCAPA and DCAPB pins, the AD7366-5/AD7367-5 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDD and VSS supplies are required for the ±12 V input range.

AD7366-5/AD7367-51是双核12位/14位、低功耗、逐次逼近型模数转换器(ADC),最高吞吐量为500 KSPS。每个器件内置两个ADC,两者之前均配有一个双通道多路复用器及一个低噪声、宽带宽采样保持放大器。

AD7366-5/AD7367-5采用ADI公司的工业CMOS工艺(iCMOS(R) )2制造,该技术平台兼具低电压和高电压CMOS的优点。利用该工艺,这些器件不仅降低了功耗和封装尺寸,而且能接受高电压双极性信号。AD7366-5/AD7367-5可以输入± 10 V范围、± 5 V范围及0 V至+10 V范围内的真双极性模拟信号。

这些器件具有2.5 V的片内基准电压,可以禁用该电压以便使用外部基准电压。如果将3 V基准电压施加于DCAPA和DCAPB引脚,则AD7366-5/AD7367-5就能接受± 12 V真双极性模拟输入。对于± 12 V输入范围,需要采用最低± 12 V的 VDD 和 VSS电源。
