TMC1175A

Video A/D Converter

8 bit, 40 Msps

Features

Description

• 8-Bit resolution

• 40 Msps conversion rate

The 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.

• Low power: 100mW at 20 Msps

• Integral track/hold

• Integral and differential linearity error 0.5 LSB

• Single or dual +5 Volt supplies

• Differential phase 0.5 degree

• Differential gain 1.5%

• Three-state TTL/CMOS-compatible outputs

• Low cost

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.

Applications

• Video digitizing

• VGA and CCD digitizing

• LCD projection panels

• Image scanners

• Personal computer video boards

• Multimedia systems

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.

• Low cost, high speed data conversion
