LTC1414

14-Bit, 2.2Msps,

Sampling A/D Converter

FEATURES

DESCRIPTIO

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

±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

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.

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

100kHz input. The performance remains high at the Nyquist

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

SFDR.

The unique differential input sample-and-hold can acquire

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

bandwidth. The 70dB common mode rejection can elimi-

nate ground loops and common mode noise by measuring

signal differentially from the source

The ADC has a microprocessor compatible, 14-bit parallel

output port. There is no pipline delay in the conversion

results.
