ADC1173
8-Bit, 3-Volt, 15MSPS, 33mW A/D Converter
General Description
The ADC1173 is a low power, 15 MSPS analog-to-digital
converter that digitizes signals to 8 bits while consuming just
33 mW of power (typ). The ADC1173 uses a unique architec-
ture that achieves 7.6 Effective Bits. Output formatting is
straight binary coding.
The excellent DC and AC characteristics of this device, to-
gether with its low power consumption and +3V single supply
operation, make it ideally suited for many video, imaging and
communications applications, including use in portable
equipment. Furthermore, the ADC1173 is resistant to latchup
and the outputs are short-circuit proof. The top and bottom of
the ADC1173’s reference ladder is available for connections,
enabling a wide range of input possibilities.
The ADC1173 is offered in SOIC (EIAJ) and TSSOP. It is de-
signed to operate over the commercial temperature range of
-20˚C to +75˚C.
