Product Details
●The AD7352 is a dual, 12-bit, high speed, low power, successive approximation ADC that operates from a single 2.5 V power supply and features throughput rates up to 3 MSPS. The part contains two ADCs, each preceded by a low noise, wide band-width track-and-hold circuit that can handle input frequencies in excess of 110 MHz.
●The conversion process and data acquisition use standard control inputs allowing for easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS; and a conversion is also initiated at this point. The conversion time is determined by the SCLK frequency.
●The AD7352 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With a 2.5 V supply and a 3 MSPS throughput rate, the part consumes 10 mA typically. The part also offers a flexible power/throughput rate management options.
●The analog input range for the part is the differential common-mode ±VREF/2. The AD7352 has an on-chip 2.048 V reference that can be overdriven when an external reference is preferred. The AD7352 is available in a 16-lead thin shrink small outline package (TSSOP).
●Product Highlights
● 1. Two Complete ADC Functions.
●These functions allow simultaneous sampling and conversion of two channels. The conversion result of both channels is simultaneously available on separate data lines or in suc-cession on one data line if only one serial port is available.
● 2. High Throughput With Low Power Consumption.
●The AD7352 offers a 3 MSPS throughput rate with 26 mW power consumption.
● 3. No Conversion Latency.
●The AD7352 features two standard successive approx-imation ADCs with accurate control of the sampling instant via aCS input and, once off, conversion control.

● Data acquisition systems
● Motion control
