AD7356BRUZ differential input, dual, simultaneous sampling, 5 MSPS, 12-bit SAR ADCSample & Purchase
The AD7356 is a dual 12 bit, high speed, low power, successive approximation (SAR) modulusconverter(ADC) operates from a single 2.5 V supply with throughput rates up to 5 MSPS. The device contains two ADCs, each preceded by a low noise, wide bandwidth track-and-hold circuit that can handle input frequencies above 110 MHz.
The conversion process and data sampling use standard control inputs that are easy to interface with a microprocessor or digital signal processor (DSP). Its input signal is sampled on the falling edge of CS while conversion begins. The conversion time is determined by the SCLK frequency.
The AD7356 uses advanced design techniques to achieve very low power at high throughput. The device operates from a 2.5 V supply, has a throughput rate of 5 MSPS, and typically consumes 14 mA of power. The device also provides flexible power and throughput management when operating in normal mode with very low quiescent current consumption.
The device uses differential inputs ranging from common-mode ± Vref/2. The AD7356 has a built-in 2.048 V reference source, or an external reference source can be used.
The AD7356 is available in a 16-lead TSSOP package
Product Focus
1. Two complete sets of ADCs allow two channels to sample and convert simultaneously.
Simultaneous sampling and conversion of two channels can be achieved. The conversion results of two channels can be obtained simultaneously by independent data lines or, if only one serial port is available, sequentially over one data line.
2. High throughput rate and low power consumption. The AD7356 provides a throughput rate of 5 MSPS while consuming 35 mW
3. No conversion delay.
The AD7356 uses two standard successive approximation ADCs to accurately control the sampling time with CS input and one-time conversion control.
