Description
The LTC2298/LTC2297/LTC2296 are 14-bit 65Msps/40Msps/25Msps, low power dual 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2298/LTC2297/LTC2296 are perfect for demanding imaging and communications applications with AC performance that includes 74.3dB SNR and 90dB SFDR for signals at the Nyquist frequency.
DC specs include ±1.2LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1LSBRMS.
A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic. An optional multiplexer allows both channels to share a digital output bus.
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.

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 LTC2297:
- 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.
- Request the DC890 FastDAACS USB Controller either online or from your local sales representative. The DC890 interfaces with the USB port of your computer and connects to the LTC2297 daughter card.
-
Request the LTC2297 (DC851A-C) from your local sales representative. This daughter card along with the QuickEval software package, allows easy evaluation of the part from your PC.
- DC851A-C, Fin = 1MHz to 70MHz
- For multiplexed output operation, Request the DC718 QuickDAATS USB Controller either online or from your local sales representative and the DC816A-B daughter card from your sales representative.
