ADC08060
8-Bit, 20 MSPS to 60 MSPS, 1.3 mW/MSPS A/D Converter
with Internal Sample-and-Hold
General Description
The ADC08060 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 70 MSPS
with outstanding dynamic performance over its full operating
range while consuming just 1.3 mW per MHz of clock fre-
quency. That's just 78 mW of power at 60 MSPS. Raising the
PD pin puts the ADC08060 into a Power Down mode where
it consumes just 1 mW.
The unique architecture achieves 7.5 Effective Bits with
25 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 ADC08060 is
resistant to latch-up and the outputs are short-circuit proof.
The top and bottom of the ADC08060'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 output coding is straight binary and the
digital inputs (CLK and PD) are TTL/CMOS compatible.
The ADC08060 is offered in a 24-lead plastic package
(TSSOP) and is specified over the industrial temperature
range of −40°C to +85°C.
