Rainbow Electronics ADC1173 - Manual

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 archi-
tecture that achieves 7.6 Effective Bits. Output formatting is
straight binary coding.
The excellent DC and AC characteristics of this device,
together 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 latch-up 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
designed to operate over the commercial temperature range
of -40˚C to +75˚C.
