DESCRIPTION

The ADC1175-50 is a low power, 50 MSPS analogto-

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

at 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 24-pin TSSOP and 24-

pin WQFN packages and is designed to operate over

the extended commercial temperature range of

−20°C to +75°C.
