GENERAL DESCRIPTION
The EB7820/24 evaluation board demonstrates the perfor-
mance of the SPT7820 and SPT7824, monolithic high speed
analog-to-digital converters (ADCs). This document can
used as an application note and as supplemental information
to the existing data sheets (SPT7820 or SPT7824). Both the
SPT7820 and SPT7824 have analog input ranges of
±
2 V.
The SPT7820 is capable of digitizing an analog input signal
into 10-bit words at a minimum update rate of 20 MSPS, while
the SPT7824 is capable of digitizing an analog input signal
into 10-bit words at a minimum update rate of 40 MSPS. Both
devices are pin-compatible. All input/output logic is TTL-
compatible.

The EB7820/24 (
≈
4" X 7.5") consists of five separate sections:
- Reference circuits
- Clock circuits
- SPT7820 or SPT7824, 10-bit ADC (not included with the board)
- Output latches available through 26-pin female ribbon connector
- The DB792 DAC reconstruction board is a separate daughter board (
≈
2.5" X 3.0") that directly interfaces with the
EB7820/24
