LTC1404 plete SO-8, 12-Bit, 600ksps ADC with Shutdown Features s s s s s s s s s s s s DESCRIPTION The LTC ®1404 is a plete 600ksps, 12-bit A/D converter which draws only 75m W from a 5V or ± 5V supplies. This easy-to-use device es plete with a 160ns sample-and-hold and a precision reference. Unipolar and bipolar conversion modes add to the flexibility of the ADC. The LTC1404 has two power saving modes: Nap and Sleep. In Nap mode, it consumes only 7.5m W of power and can wake up and convert immediately. In the Sleep mode, it consumes 60µW of power typically. Upon powerup from Sleep mode, a reference ready (REFRDY) signal is available in the serial data word to indicate that the reference has settled and the chip is ready to convert. The LTC1404 converts 0V to 4.096V unipolar inputs from a single 5V supply and ± 2.048V bipolar inputs from ± 5V supplies. Maximum DC specs include ± 1LSB INL, ± 1LSB DNL and 45ppm/°C full-scale drift over temperature. Guaranteed AC performance includes 69d B S/(N + D) and - 76d B THD at an input frequency of 100k Hz over temperature. 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.
