LTC1404 TA01
Single 5V Supply, 600kHz, 12-Bit Sampling A/D Converter
The LTC
1404 is a complete 600ksps, 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 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 7.5mW of power
and can wake up and convert immediately. In the Sleep
mode, it consumes 60
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 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 69dB 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.
