The AD7357 is a dual, 14-bit, high speed, low power, successive approximation ADC that operates from a single 2.5 V power supply and features throughput rates of up to 4.2 MSPS. The part contains two ADCs, each preceded by a low noise, wide bandwidth 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; conversion is also initiated at this point. The conversion time is determined by the SCLK frequency.
The AD7357 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With a 2.5 V supply and a 4.2 MSPS throughput rate, the device consumes 14 mA typically. The part also offers flexible power/throughput rate management when operating in normal mode as the quiescent current consumption is so low.
The analog input range for the device is the differential common mode ±VREF/2. The AD7357 has an on-chip 2.048 V reference that can be overdriven when an external reference is preferred.
The AD7357 is available in a 16-lead thin shrink small outline package (TSSOP) and an 18-lead lead frame chip scale package (LFCSP).
Product Highlights
- 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 succession on one data line if only one serial port is available. - High Throughput with Low Power Consumption.
The AD7357 offers a 4.2 MSPS throughput rate with 36 mW power consumption. - Simultaneous Sampling.
The part features two standard successive approximation ADCs with accurate control of the sampling instant via a CS input and once off conversion control.
Applications
- Automotive radar
- Data acquisition systems
- Motion control
- I and Q demodulation
- RFID readers
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
