ADC08200
8-Bit, 20 MSPS to 200 MSPS, 1.05 mW/MSPS A/D
Converter with Internal Sample-and-Hold
General Description
The ADC08200 is a low-power, 8-bit, monolithic analog-to-
digital converter with an on-chip track-and-hold circuit. Opti-
mized for low cost, low power, small size and ease of use,
this product operates at conversion rates up to 230 MSPS
while consuming just 1.05 mW per MHz of clock frequency,
or 210 mW at 200 MSPS. Raising the PD pin puts the
ADC08200 into a Power Down mode where it consumes
about 1 mW.
The unique architecture achieves 7.3 Effective Bits with
50 MHz input frequency. The ADC08200 is resistant to
latch-up and the outputs are short-circuit proof. The top and
bottom of the ADC08200’s reference ladder are available for
connections, enabling a wide range of input possibilities. The
digital outputs are TTL/CMOS compatible with a separate
output power supply pin to support interfacing with 3V or
2.5V logic. The digital inputs (CLK and PD) are TTL/CMOS
compatible. The output data format is straight binary.
The ADC08200 is offered in a 24-lead plastic package
(TSSOP) and, while specified over the industrial temperature
range of −40˚C to +85˚C, it will function over the to −40˚C to
+105˚C temperature range. An evaluation board is available
to assist in the easy evaluation of the ADC08200.
