Description

The LTC2228/LTC2227/LTC2226 are 12-bit 65Msps/40Msps/25Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2228/LTC2227/LTC2226 are perfect for demanding imaging and communications applications with AC performance that includes 71dB SNR and 80dB SFDR for signals at the Nyquist frequency.

DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.25LSBRMS.

A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6Vlogic.

A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.

Simulate

Linear Technology offers free software and demo boards that greatly simplify the task of testing and evaluating our data converters. To use these powerful tools with the LTC2227:

  1. Download the PScope (QuickEval II) System software. The PScope System is a USB-based product demonstration and data acquisition system for use with Linear Technologys high performance analog to digital converters. The software also includes web links to the appropriate device data sheets and provides an automatic update feature to keep the software current with the latest set of device drivers.

  2. Request the DC718 QuickDAATS USB Controller either online or from your local sales representative. The DC718 QuickDAATs USB Controller interfaces with the USB port of your computer and connects to the LTC2227 daughter card.

  3. Request the DC782A-H daughter card from your local sales representative. The DC782A-H allows easy evaluation of the LTC2227 from your PC.
