36-Pin SSOP Package (0.209 Inch Width)

The LTC

1740 is a 6Msps, 14-bit sampling A/D converter

that draws only 245mW from either a single 5V or dual

±5V

supplies. This easy-to-use device includes a high

dynamic range sample-and-hold and a programmable

precision reference.

The LTC1740 has a flexible input circuit that allows differ-

ential full-scale input ranges of

±2.5V

and

±1.25V

with the

internal reference, or any full-scale input range up to

±2.5V

with an external reference. The input common

mode voltage is arbitrary, though a 2.5V reference is

provided for single supply applications.

DC specifications include 1LSB typical INL, 0.5LSB typical

DNL and no missing codes over temperature. Outstanding

AC performance includes 79dB S/(N + D) and 91dB SFDR

at an input frequency of 2.5MHz.

The unique differential input sample-and-hold can acquire

single-ended or differential input signals up to its 80MHz

bandwidth. The 75dB common mode rejection allows

users to eliminate ground loops and common mode noise

by measuring signals differentially from the source. A

separate output logic supply allows direct connection to

3V components.
