FEATURES Dual 12-bit, 2-channel ADC True Bipolar Analog Inputs Programmable Input Ranges ±10, ±5, 0 to 10 V Throughput rate: 1 MSPS Simultaneous conversion with read in less than 1μs Specified for VCC of 5 V±5% Low current consumption: 5.65 mA max Wide input bandwidth 70 dB SNR at 50 kHz input frequency On-chip reference: 2.5 V –40°C to +85°C operation High speed serial interface SPI®/QSPI™/MICROWIRE™/DSP compatible iCMOSTM Process Technology 24-lead TSSOP package For 14 bit version see AD7367 GENERAL DESCRIPTION The AD73661 is a dual, 12-bit, high speed, low power, successive approximation ADC that features 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 that can handle input frequencies in excess of 10 MHz. The AD7366 is fabricated on Analog Devices’ Industrial CMOS process, iCMOS, a technology platform combining the advantages of low and high voltage CMOS, bipolar and high voltage DMOS processes. The process allows the AD7366 to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366 can accept true bipolar analog input signals in the ±10 V range, ±5 V range and 0 to 10 V range. The AD7366 has an on-chip 2.5 V reference that can be overdriven if an external reference is preferred. The AD7366 is available in a 24-lead TSSOP package. iCMOSTM 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 30V and operating at +/- 15V supplies while allowing dramatic reductions in power consumption and package size, and increased AC and DC performance. 1Protected by U.S. Patent No. 6,681,332.
