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 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.
