Linear Technology LTC2351-14 Quic Start Manual

QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1278
DESCRIPTION
Demonstration circuit 1278 features the LTC2351-14
6-channel, 14-Bit, simultaneous sampling ADC. Total
throughput is 1.5MSPS; 250KSPS per channel, with a
typical channel-to-channel aperture skew of 200ps.
The board is designed to be used with the DC890B
Fast DAACS data collection board to show the AC
performance of the LTC2351-14. Alternatively, the
QUICK START PROCEDURE
BASIC CONNECTIONS
Connect DC1278 to a DC890B USB High Speed Data
Collection Board using connector J2. Connect
DC890B to a host PC with a standard USB A/B cable.
Apply 5-7V DC to the VIN and GND terminals. Apply a
25MHz 3.3Vp-p sine wave or square wave to connec-
6-CHANNEL, 14-BIT, 1.5MSPS SIMULTANEOUS SAMPLING ADC
board can be directly connected to an application to
evaluate the ADC's performance.
Design files for this circuit board are available. Call
the LTC factory.
