ADC1175 Datasheet | National Semiconductor

Description The ADC1175 is a low power, 20 Msps analog-to-digital converter that digitizes signals to 8 bits while consuming just 60 m W of power (typ). The ADC1175 uses a unique architecture that achieves 7.5 Effective Bits. Output formatting is straight binary coding. The excellent DC and AC characteristics of this device, together with its low power consumption and +5V single supply operation, make it ideally suited for many video, imaging and munications applications, including use in portable equipment. Furthermore, the ADC1175 is resistant to latchup and the outputs are short-circuit proof. The top and bottom of the ADC1175’s reference ladder is available for connections, enabling a wide range of input possibilities. The ADC1175 is offered in SOIC (EIAJ) and TSSOP. It is designed to operate over the mercial temperature range of -20˚C to +75˚C.
