AD7367BRUZ-RL7

真双极性输入，双1レS， 12 / 14位，双通道SAR型ADC True Bipolar Input, Dual 1 レs, 12-/14-Bit, 2-Channel SAR ADCs

Product Details

The AD7366/AD7367 are dual 12-bit/14-bit, high speed, low power, successive approximation analog-to-digital converters ADCs that feature throughput rates up to 1 MSPS. The device contains two ADCs, each preceded by a 2-channel multiplexer, and a low noise, wide bandwidth track-and-hold amplifier.

The AD7366/AD7367 are fabricated on the Analog Devices, Inc., industrial CMOS process iCMOS1, which is a technology platform combining the advantages of low and high voltage CMOS. The iCMOS process allows the AD7366/AD7367 to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366/AD7367 can accept true bipolar analog input signals in the ±10 V range, ±5 V range, and 0 V to 10 V range.

The AD7366/AD7367 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/AD7367 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDD and VSS supplies are required for the ±12 V input range.

**Product Highlights**

1. The AD7366/AD7367 can accept true bipolar analog input signals, as well as ±10 V, ±5 V, ±12 V with external reference, and 0 V to 10 V unipolar signals.

2. Two complete ADC functions allow simultaneous sampling and conversion of two channels.

3. 1 MSPS serial interface: SPI-/QSPI-/DSP-/MICROWIRE-compatible interface.

2 _i_CMOS Process Technology. For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels, _i_CMOS is a technology platform that enables the development of analog ICs capable of 30 V and operating at ±15 V supplies while allowing dramatic reductions in power consumption and package size, and increased ac and dc performance.
