ADC1175-50

8-Bit, 50 MSPS, 125 mW A/D Converter

General 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 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 TSSOP and LLP (a molded

lead frame-based chip-scale package) and is designed to

operate over the extended commercial temperature range of

−20˚C to +75˚C.
