FEATURES

DESCRIPTION

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

•

Internal Track-and-Hold Function

to-digital converter that digitizes signals to 8 bits while

•

Single +5V Operation

consuming just 125 mW (typ). The ADC1175-50 uses

•

Internal Reference Bias Resistors

a unique architecture that achieves 6.8 Effective Bits

at 25 MHz input and 50 MHz clock frequency. Output

•

Industry Standard Pinout

formatting is straight binary coding.

•

Power-Down Mode (<5 mW)

The excellent DC and AC characteristics of this

device, together with its low power consumption and

APPLICATIONS

+5V single supply operation, make it ideally suited for

•

Digital Still Cameras

many video and imaging applications, including use in

•

CCD Imaging

portable equipment. Furthermore, the ADC1175-50 is

resistant to latch-up and the outputs are short-circuit

input capacitance (7 pF, typical) makes this device

easier to drive than conventional flash converters and

KEY SPECIFICATIONS

the power down mode reduces power consumption to

•

Resolution 8 Bits

less than 5 mW.

•

Maximum Sampling Frequency 50 MSPS (min)

The ADC1175-50 is offered in 24-pin TSSOP and 24-

•

THD 54 dB (typ)

pin WQFN packages and is designed to operate over

•

DNL 0.7 LSB (typ)

the extended commercial temperature range of

−20°C to +75°C.

•

•

Ensured No Missing Codes

•

Power Consumption (Excluding

Reference Current) 125 mW (typ)

190 mW (max)
