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 5Vsupply.Anonboardhighperformancesample-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.

Single Supply 5V or 5V ꢀperation

Sample Rate: 200ksps

1ꢁ25LSB ꢂIL anꢃ 1LSB DIL ꢄaM

Power Dissipation: 15mW (Typ)

Parallel or Serial Data ꢀutput

No Missing Codes Over Temperature

Power Shutdown: Nap and Sleep

External or Internal Reference

Differential High Impedance Analog Input

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.

Input Range: 0V to 4.096V or 2.048V

81.5dB S/(N + D) and –94dB THD at Nyquist

28-Lead SSOP Package

APPLICATIONS

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.
