LTC1400
Complete SO-8, 12-Bit,
400ksps ADC with Shutdown
The LTC
1400 is a complete 400ksps, 12-bit A/D con-
verter 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 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 30
μ
W 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.
