ADC1175 General Description
The ADC1175 is a low power, 20 Msps analog-to-digital converter that digitizes signals to 8 bits while consuming just 60 mW 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 suppl yoperation, make it ideally suited for many video, imaging and communications 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 commercial temperature range of -20 to +75.
