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.

1iCMOS Process Technology. For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels, iCMOS 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.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
