LTC1418

Low Power, 14-Bit, 200ksps

ADC with Serial and Parallel I/O

FEATURES

DESCRIPTION

The

LTC

1418

is a low power, 200ksps, 14-bit A/D con-

verter. Data output is selectable for 14-bit parallel or serial

format. This versatile device can operate from a single 5V

or ±5V supply. An onboard high performance sample-and-

hold, a precision reference and internal timing minimize

external circuitry requirements. The low 15mW power

dissipation is made even more attractive with two user

selectable power shutdown modes.

The LTC1418 converts 0V to 4.096V unipolar inputs from

a single 5V supply and ±2.048V bipolar inputs from ±5V

supplies. DC specs include ±1.25LSB INL, ±1LSB DNL

and no missing codes over temperature. Outstanding AC

performance includes 82dB S/(N + D) and 94dB THD at

the Nyquist input frequency of 100kHz.

The flexible output format allows either parallel or serial

I/O. The SPI/MICROWIRE compatible serial I/O port can

operate as either master or slave and can support clock

frequencies from DC to 10MHz. A separate convert start

input and a data ready signal (BUSY) allow easy control

of conversion start and data transfer.
