LTC1402
Serial 12-Bit, 2.2Msps
Sampling ADC with Shutdown
October 1999
DESCRIPTION
The LTC
廬
1402 is a 12-bit, 2.2Msps sampling A/D con-
verter. This high performance device includes a high dy-
namic range sample-and-hold and a precision reference.
It operates from a single 5V supply or dual
鹵5V
supplies
and draws only 90mW from 5V.
The versatile differential input offers a unipolar range of
4.096V and a bipolar range of
鹵2.048V
for dual supply
systems where high performance op amps perform best,
eliminating the need for special translation circuitry.
The high common mode rejection allows users to elimi-
nate ground loops and common mode noise by measuring
signals differentially from the source.
Outstanding AC performance includes 72dB S/(N + D) and
鈥?3dB SFDR at the Nyquist input frequency of 1.1MHz
with dual
鹵5V
supplies and 鈥?4dB SFDR with a single 5V
supply.
The LTC1402 has two power saving modes: Nap and
Sleep. Nap mode consumes only 15mW of power and
Sleep can wake up and convert immediately. In Sleep
mode, it typically consumes 10碌W of power. 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 3-wire serial port allows compact and efficient data
transfer to a wide range of microprocessors, microcon-
trollers and DSPs. A digital output driver power supply pin
allows direct connection to 3V or lower logic.
Sample Rate: 2.2Msps
