Description
The TMC1173A/1273 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 fre-
quency components up to 5 MHz. The innovative architec-
ture and submicron CMOS technology limit typical power
dissipation to 15 mW.
The TMC1173A/1273 operates from a single +2.7 to +3.6
Volt power supply and has internal voltage reference resis-
tors for self-bias operation. Input capacitance is very low,
simplifying or eliminating input driving amplifiers. All digi-
tal three-state outputs are 3V TTL- and CMOS-compatible.
The TMC1173A and TMC1273 share their core architec-
tures; the TMC1273 adds two overrange outputs that indicate
when the analog input signal is beyond the conversion range.
The TMC1173A/1273 is available in 24-pin plastic DIP,
24-lead plastic SOIC, and 28-lead J-lead PLCC packages.
