LTC1412

12-Bit, 3Msps,

Sampling A/D Converter

FEATURES

DESCRIPTION

The LTC^®1412 is a 12-bit, 3Msps, sampling A/D con-

verter. This high performance device includes a high

dynamic range sample-and-hold and a precision refer-

ence. Operating from ±5V supplies it draws only 150mW.

■

Sample Rate: 3Msps

■

72dB S/(N + D) and 82dB SFDR at Nyquist

■

±0.35LSB INL and ±0.25LSB DNL (Typ)

■

Power Dissipation: 150mW

■

External or Internal Reference Operation

The ±2.5V input range is optimized for low noise and low

distortion. Most high performance op amps also perform

bestoverthisrange, allowingdirectcouplingtotheanalog

inputs and eliminating the need for special translation

circuitry. Outstanding AC performance includes 72dB

S/(N + D) and 82dB SFDR at the Nyquist input frequency

of 1.5MHz.

■

True Differential Inputs Reject Common Mode Noise

■

40MHz Full Power Bandwidth Sampling

■

±2.5V Bipolar Input Range

■

No Pipeline Delay

■

28-Pin SSOP Package

APPLICATIONS

Theuniquedifferentialinputsample-and-holdcanacquire

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

bandwidth. The 60dB common mode rejection allows

users to eliminate ground loops and common mode noise

by measuring signals differentially from the source.

is no pipeline delay in the conversion results. A separate

convert start input and converter status signal (BUSY)

ease connections to FIFOs, DSPs and microprocessors. A

digital output driver power supply pin allows direct con-

nection to 3V logic.
