The LTC1400 is a complete 400ksps, 12-bit A/D converter which draws only 75mW from a 5V or ±5V supplies. This easy-to-use device comes complete with a 200ns sample-and-hold and a precision reference. Unipolar and bipolar conversion modes add to the flexibility of the ADC. The LTC1400 is capable of going into two power saving modes: NAP and SLEEP. In NAP mode, it consumes only 6mW of power and can wake up and convert immediately. In the SLEEP mode, it consumes 30µW of power typically. Upon power-up 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 LTC1400 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 drift over temperature. Guaranteed AC performance includes 70dB S/(N D) and 76dB THD at an input frequency of 100kHz, over temperature.
The 3-wire serial port allows compact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs.
