LTC1419

14-Bit, 800ksps Sampling

A/D Converter with Shutdown

FEATURES

DESCRIPTIO

The LTC^®1419 is a 1µs, 800ksps, 14-bit sampling

A/D converter that draws only 150mW from ±5V supplies.

This easy-to-use device includes a high dynamic range

sample-and-hold and a precision reference. Two digitally

selectable power shutdown modes provide flexibility for

low power systems.

■

Sample Rate: 800ksps

■

Power Dissipation: 150mW

■

81.5dB S/(N + D) and 93dB THD

■

No Missing Codes

No Pipeline Delay

■

Nap and Sleep Shutdown Modes

■

Operates with 2.5V Internal 15ppm/°C

The LTC1419 has a full-scale input range of ± 2.5V. Out-

standing AC performance includes 81.5dB S/(N + D) and

93dB THD with a 100kHz input; 80dB S/(N + D) and 86dB

THD at the Nyquist input frequency of 400kHz.

Reference or External Reference

■

True Differential Inputs Reject Common Mode Noise

■

20MHz Full-Power Bandwidth Sampling

Bipolar Input Range: ±2.5V

28-Pin SSOP and SO Packages

■

Theuniquedifferentialinputsample-and-holdcanacquire

single-ended or differential input signals up to its 20MHz

bandwidth. The 60dB common mode rejection allows

users to eliminate ground loops and common mode noise

by measuring signals differentially from the source.

APPLICATIO S

■

Telecommunications

■

Digital Signal Processing

The ADC has a µP compatible, 14-bit parallel output port.

There is no pipeline delay in the conversion results. A

separate convert start input and data ready signal (BUSY)

ease connections to FIFOs, DSPs and microprocessors.
