Description
Incorporated into the TMC1203 are three analog-to-digital
(A/D) converters, each with independent clocks and refer-
ence voltages. 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 architecture conversion
architecture and submicron CMOS technology reduce typi-
cal power dissipation 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.
TMC1203 package is a 80-lead Metric Quad Flat Pack
(MQFP). Performance specifications are guaranteed from
0°C to 70°C.
