Part Description

Figure 1. The AD72651 is a dual, 12-bit, high speed, low power, successive approximation ADC that operates from a single 2.7 V to 5.25 V power supply and features throughput rates of up to 1 MSPS. The device contains two ADCs, each preceded by a 3-channel multiplexer, and a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 30 MHz. PRODUCT HIGHLIGHTS 1. Two Complete ADC Functions Allow Simultaneous Sampling and Conversion of Two Channels. Each ADC has three fully/pseudo differential pairs, or six single-ended channels, as programmed. The conversion result of both channels is simultaneously available on separate data lines, or in succession on one data line if only one serial port is available. The conversion process and data acquisition use standard control inputs allowing easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS; conversion is also initiated at this point. The conversion time is determined by the SCLK frequency. The AD7265 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With 5 V supplies and a 1 MSPS throughput rate, the part consumes 4 mA maximum. The part also offers flexible power/throughput rate management when operating in normal mode, because the quiescent current consumption is so low. 2. High Throughput with Low Power Consumption. The AD7265 offers a 1 MSPS throughput rate with 9 mW maximum power dissipation when operating at 3 V. 3. The AD7265 offers both a standard 0 V to VREF input range and a 2 × V input range. REF 4. No Pipeline Delay. The part features two standard successive approximation ADCs with accurate control of the sampling instant via a The analog input range for the part can be selected to be a 0 V to V CS input and once off conversion control. (or 2 × V REF REF) range, with either straight binary or twos complement output coding. The AD7265 has an on-chip 2.5 V reference that can be overdriven when an external reference is preferred. This external reference range is 100 mV to V 1 Protected by U.S. Patent No. 6,681,332. DD. The AD7265 is available in 32-lead LFCSP and 32-lead TQFP.
