AD7366BRUZ

• Product introduction

AD7366 BRUZ true bipolar input, dual-core 12-bit, dual-channel, simultaneous sampling SAR ADC

The AD7366/AD7367 are dual-core 12-bit/14-bit, high speed, low power, successive approximation analogsconverter(ADC) with throughput up to 1 MSPS. The device contains two ADCs, both preceded by a dual multiplexer and a low noise, wide bandwidth track-and-hold amplifier.

The AD7366/AD7367 use Analog Devices, Inc. industrial CMOS process (iCMOS).¹ ), this technology platform combines the advantages of low-voltage and high-voltage CMOS. Using the iCMOS process, the AD7366/AD7367 not only reduces power dissipation 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 an on-chip reference of 2.5 V that can be disabled to allow the use of an external reference. If a reference voltage of 3 V is applied to the DCAPA and DCAPB pins, the AD7366/AD7367 can accept ± 12 V true bipolar analog inputs. For ±12 V input range, a minimum ±12 V V is required_DD and V_SS Power supply.

Product Focus

1. The AD7366/AD7367 can input true bipolar analog signals as well as unipolar signals ± 10 V, ±5 V, ±12 V using an external reference, and 0 V to 10 V.
2. Two complete ADC functions enable simultaneous sampling and conversion of both channels.
3. 1 MSPS SERIAL INTERFACE: SPI/QSPI/DSP/MICROWIRE COMPATIBLE INTERFACE.

¹ iCMOS 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 30 V supplies and operate at ± 15 V while significantly reducing power consumption, package size, and AC and DC performance.
