The AD7324 is a 4-channel, 12-bit plus sign, successive approximation ADC designed on theiCMOS (industrial CMOS) process.iCMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage parts could achieve. Unlike analog ICs using conventional CMOS processes,iCMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption, and reduced package size.The AD7324 can accept true bipolar analog input signals. The AD7324 has four software-selectable input ranges: ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. Each analog input channel can be independently programmed to one of the four input ranges. The analog input channels on the AD7324 can be programmed to be single-ended, true differential, or pseudo differential.The ADC contains a 2.5 V internal reference. The AD7324 also allows for external reference operation. If a 3 V reference is applied to the REFIN/OUT pin, the AD7324 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDDand VSSsupplies are required for the ±12 V input range. The ADC has a high speed serial interface that can operate at throughput rates up to 1 MSPS.PRODUCT HIGHLIGHTSThe AD7324 can accept true bipolar analog input signals, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V unipolar signals.The four analog inputs can be configured as four single-ended inputs, two true differential input pairs, two pseudo differential inputs, or three pseudo differential inputs.1 MSPS serial interface.

The AD73311 and AD73311L are complete front-end processors for general-purpose applications including speech and telephony. They feature a 16-bit A/D conversion channel and a 16-bit D/A conversion channel. Each channel provides 70 dB signal-to-noise ratio over the voiceband signal bandwidth. The AD73311L is a follow-on to the AD73311 with improved on-chip filtering, more sample-rate options and lower cost. The L version operates from 3.0 V only, where as the AD73311 operates from either 3 V or 5 V power supplies.The gains of the A/D and D/A conversion channels are programmable over 38 dB and 21 dB respectively. An on-chip reference voltage is included to allow single-supply operations. A serial port (SPORT) allows easy interfacing for single or cascaded devices to industry standard DSP engines.The AD73311 and AD73311L are suitable for a variety of applications in the speech and telephony areas including low-bit rate, high quality compression, speech enhancement, recognition and synthesis. The low group delay characteristic of the part makes it suitable for single or multi-channel active-control applications.APPLICATIONSGeneral Purpose Analog I/OSpeech ProcessingCordless and Personal CommunicationsTelephonyActive Control of Sound & VibrationData Communications
