Rainbow Electronics ADC08L060 - Manual

ADC08L060
8-Bit, 10 MSPS to 60 MSPS, 0.65 mW/MSPS A/D
Converter with Internal Sample-and-Hold
General Description
The ADC08L060 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 10 MSPS to
60 MSPS while consuming just 0.65 mW per MHz of clock
frequency, or 39 mW at 60 MSPS. Raising the PD pin puts
the ADC08L060 into a Power Down mode where it con-
sumes about 1 mW.
The unique architecture achieves 7.6 Effective Bits. The
ADC08L060 is resistant to latch-up and the outputs are
short-circuit proof. The top and bottom of the ADC08L060s
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 1.8V to 3V logic. The digital
inputs (CLK and PD) are TTL/CMOS compatible.
The ADC08L060 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 evaluation of the ADC08L060.
