LTC1414

14-Bit, 2.2Msps,

Sampling A/D Converter

FEATURES

DESCRIPTIO

The LTC^®1414 is a 14-bit, 2.2Msps, sampling A/D con-

verter which draws only 175mW from ±5V supplies. This

high performance ADC includes a high dynamic range

sample-and-hold, a precision reference and requires no

external components.

■

Sample Rate: 2.2Msps

Outstanding Spectral Purity:

■

80dB S/(N + D) and 95dB SFDR at 100kHz

78dB S/(N + D) and 84dB SFDR at Nyquist

■

Ultralow Distortion with Single-Ended or

Differential Inputs

The LTC1414’s high performance sample-and-hold has a

full-scale input range of ±2.5V. Outstanding AC perfor-

mance includes 80dB S/(N + D) and 95dB SFDR with a

100kHzinput.TheperformanceremainshighattheNyquist

input frequency of 1.1MHz with 78dB S/(N + D) and 84dB

SFDR.

■

±2.5V Bipolar Input Range Eliminates Level Shifting

and Rail-to-Rail Op Amp Requirements

■

Easy Hookup for External or Internal Reference

■

No Pipeline Delay

■

Power Dissipation: 175mW on ±5V Supplies

■

28-Pin Narrow SSOP Package

Theuniquedifferentialinputsample-and-holdcanacquire

single-ended or differential input signals up to its 40MHz

bandwidth. The 70dB common mode rejection can elimi-

nategroundloopsandcommonmodenoisebymeasuring

signal differentially from the source
