The LTC1400IS8#PBF is a complete 12-bit Analog-to-digital Converter (ADC) with shutdown. 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 has two power saving modes of 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 0 to 4.096V unipolar inputs from a single 5V supply and ±2.048V bipolar inputs from ±5V supplies. The 3-wire serial port allows compact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs.
- No missing codes over temperature
- High impedance analog input
- Internal reference can be overdriven externally
