DescriptionThe TMC1175A analog-to-digital (A/D) converter employs
a two-step flash architecture to convert analog signals into
8-bit digital words at sample rates of up to 40 Msps
(Megasamples per second). An integral Track/Hold circuit
delivers excellent performance on signals with full-scale fre-
quency components up to 12 MHz. Innovative architecture
and submicron CMOS technology limit typical power dissi-
pation to 100 mW.
Power may be derived from either single or dual +5V
supplies. Internal voltage reference resistors allow self-bias
operation. Input capacitance is very low, simplifying or
eliminating input driving amplifiers. All digital three-state
outputs are TTL- and CMOS-compatible.
The TMC1175A is available in 24-lead plastic SOIC, and
28-lead J-lead PLCC packages. Performance specifications
are guaranteed from -20°C to 75°C.
