EVAL-AD7366SDZ

• Product Introduction

EVAL-AD7366SDZ True Bipolar Input, Dual-Core 12-Bit, Dual-Channel, Simultaneously Sampling SAR ADC 

The AD7366/AD7367 are dual-core 12-bit/14-bit, high-speed, low-power, successive approximation analog-to-digital converters (ADCs) with throughput up to 1 MSPS. The device has two ADCs in it, both previously equipped with a dual-channel multiplexer and a low-noise, wide-bandwidth sample-and-hold amplifier.

The AD7366/AD7367 are manufactured using Analog Devices' industrial CMOS process (iCMOS1), a technology platform that combines the benefits of both low-voltage and high-voltage CMOS. Using the iCMOS process, the AD7366/AD7367 not only reduces power consumption and package size, but also accepts high-voltage bipolar signals. The AD7366/AD7367 can input true bipolar analog signals ± the 10 V range, ±5 V range, and 0 V to 10 V range.

The AD7366/AD7367 have a 2.5 V on-chip reference that can be disabled in order to use an external reference. If a 3 V reference is applied to the DCAPA and DCAPB pins, the AD7366/AD7367 accepts ± 12 V true bipolar analog input. For ± 12 V input range, VDD and VSS supplies with a minimum ± of 12 V are required.

Product Focus

1. AD7366/AD7367可以输入真双极性模拟信号以及±10 V、±5 V、±12 V（使用外部基准电压）和0 V至10 V范围内的单极性信号。
2. 具备两个完整的ADC功能，可以实现两个通道同时采样和转换。
3. 1 MSPS串行接口：SPI/QSPI/DSP/MICROWIRE兼容接口。

1iCMOS process technology. For analog system designers of industrial/instrumentation OEMs who need high-performance ICs that can operate at higher voltages, iCMOS is a technology platform that enables the development of analog ICs that can operate from a 30 V supply and an operating voltage of ± 15 V, while significantly reducing power consumption, reducing package size, and improving AC and DC performance.
