Description
Incorporated into the TMC1103 are three analog-to-digital
(A/D) converters, each with an independent clock, reference
voltage and input clamp. Analog signals are converted to
Triple 8-bit digital words at sample rates up to 50 Msps
(Megasamples per second) per channel.
Integral Track/Hold circuits deliver excellent performance
on signals with full-scale spectral components up to
12 MHz. Innovative two-step conversion architecture and
submicron CMOS technology reduce typical power dissipa-
tion to 100 mW per converter.
Power is derived from a single +5 Volt power supply. Out-
puts are three-state outputs and TTL/CMOS-compatible.
TMC1103 package is a 80-lead Metric Quad Flat Pack
(MQFP). Performance specifications are guaranteed from
0°C to 70°C.
