Description

The TMC1273 analog-to-digital (A/D) converter employs a two-step architecture to convert analog signals into 8-bit digital words at sample rates of up to 20 Msps (Megasamples per second). An integral Track/Hold circuit delivers excellent performance on signals with full-scale frequency components up to 5 MHz. The innovative architecture and submicron CMOS technology limit typical power dissipation to 15 mW.

The TMC1273 operates from a single +2.7 to +3.6 Volt power supply and has internal voltage reference resistors for self-bias operation. Input capacitance is very low, simplifying or eliminating input driving amplifiers. All digital three-state outputs are 3V TTL- and CMOS-compatible.

The TMC1173A and TMC1273 share their core architectures; the TMC1273 adds two overrange outputs that indicate when the analog input signal is beyond the conversion range.

The TMC1273 is available in 24-pin plastic DIP, 24-lead plastic SOIC, and 28-lead J-lead PLCC packages. Performance specifications are guaranteed from -20°C to 75°C.
