Features s s s s s s s s s s s s s LTC1401 plete SO-8, 12-Bit, 200ksps ADC with Shutdown DESCRIPTION The LTC ®1401 is a plete 200ksps, 12-bit A/D converter that converts 0V to 2.048V unipolar input and draws only 15m W from a single 3V supply. This easy-to-use device es plete with a 315ns sample-and-hold and a precision reference. Maximum DC specifications include ±1LSB INL, ±1LSB DNL and 45ppm/°C full-scale drift over temperature. The LTC1401 has three power saving modes: Nap and Sleep, through the serial interface and Shutdown by setting the SHDN pin to zero. In Nap mode, it consumes only 1.5m W of power and can wake up and convert immediately. In Sleep (Shutdown) mode, it consumes 19.5µW (13.5µW) of power typically. Upon power-up from Sleep or Shutdown mode, a reference ready (REFRDY) signal is available in the serial word to indicate that the reference has settled and the chip is ready to convert. The 3-wire serial port allows pact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs. , LTC and LT are registered trademarks of Linear Technology Corporation.
