The LTC
®
1400 is a complete 400ksps, 12-bit A/D converter
which draws only 75mW from 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 has 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, microcon-
trollers and DSPs.
