Typical Application
Description
The LTC®1609 is a 200ksps, serial sampling 16-bit A/D converter that draws only 65mW (typical) from a single 5V supply. This easy-to-use device includes a sample-and- hold, a precision reference, a switched capacitor successive approximation A/D and trimmed internal clock.
The input range is specified for bipolar inputs of ±10V, ±5V and ±3.3V and unipolar inputs of 0V to 10V, 0V to 5V and 0V to 4V. Maximum DC specs include ±2LSB INL and 16-bit no missing codes overtemperature. It has a typical signal-to-noise ratio of 87dB.
The ADC has a high speed serial interface. The serial output data can be clocked out using either the internal serial shift clock or be clocked out by an external shift clock. A separate convert start input(R/C) and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
