Description

The ADC1175-50 is a low power, 50 MSPS analog-to-digital converter that digitizes signals to 8 bits while consuming just 125 mW (typ). The ADC1175-50 uses a unique architecture that achieves 6.8 Effective Bits and 25 MHz input and 50 MHz clock frequency. 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 and imaging applications, including use in portable equipment. Furthermore, the ADC1175-50 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC1175-50's reference ladder is available for connections, enabling a wide range of input possibilities. The low input capacitance (7 pF, typical) makes this device easier to drive than conventional flash converters and the power down mode reduces power consumption to less than 5 mW.

The ADC1175-50 is offered in SOIC (EIAJ) and TSSOP. It is designed to operate over the commercial temperature range of -20 to +75.
