ADC08100
8-Bit, 20 Msps to 100 Msps, 1.3 mW/Msps A/D Converter
General Description
The ADC08100 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 of 20 Msps to
100 Msps with outstanding dynamic performance over its full
operating range while consuming just 1.3 mW per MHz of
clock frequency. That's just 130 mW of power at 100 Msps.
Raising the PD pin puts the ADC08100 into a Power Down
mode where it consumes just 1 mW.
The unique architecture achieves 7.4 Effective Bits with
41 MHz input frequency. The excellent DC and AC charac-
teristics of this device, together with its low power consump-
tion and single +3V supply operation, make it ideally suited
for many imaging and communications applications, including
use in portable equipment. Furthermore, the ADC08100 is
resistant to latch-up and the outputs are short-circuit proof.
The top and bottom of the ADC08100's reference ladder are
available for connections, enabling a wide range of input pos-
sibilities. 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 format is straight binary
The ADC08100 is offered in a 24-lead plastic package
(TSSOP) and is specified over the industrial temperature
range of −40°C to +85°C. An evaluation board is available to
assist in the product evaluation process.
