描述 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 supply operation, make it ideally suited for many video, imaging and communications applications, including use in portable equipment. Furthermore, the ADC1175 is resistant to latch-up 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 a TSSOP. It is designed to operate over the commercial temperature range of -20°C to +75°C.
