DAC-1025
10-Bit, 250MSPS, Low-Power D/A Converters
PRODUCT OVERVIEW
The 10-Bit DAC-1025 is one in a series of high speed pin
to pin compatible 10 to 10 bit D/A’s from DATEL.This D/A

The DAC-1025 operates from a single +3Volt supply
and contains a precision internal 1.24Volt reference with

mented current source topology that is built on an advanced external reference. Excellent dynamic performance, a power
CMOS process and delivers a low glitch energy outputof 2mA saving "sleep-mode" feature as well as edge-triggered
to 20mA.
LVCMOS input latches makes theTSSOP version of this family
pin-to-pin compatible with several industry DACs.

the operating temperature ranges of -40°C to +105°C
(Enhanced) or –55°C to +125°C (military). Burn-in and
environmental screening are also available.

DC characteristics of the DAC more stable in environments
where humidity is a concern.In addition, the LCC pack-
age isolates the IC from the stresses that may occur
on the printed circuit board caused by variations in
temperature.
