DESCRIPTION

The ADC08100 is a low-power, 8-bit, monolithic

analog-to-digital converter with an on-chip track-and-

hold circuit. Optimized 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 characteristics of this device, together with its low

power consumption 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 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

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.
