Data Sheet

AS1504, AS1505

Octal 8-Bit Programmable Low-Power DACs with

Shutdown and Mid-Scale Reset

1 General Description

2 Key Features

ꢀ 8 Individually-Controlled DACs

The AS1504/AS1505 are low-power (5µA @ 5V) individ-

ually programmable 8-channel, 8-bit resolution digital-to-

analog converters. All eight DACs share a common ref-

erence-voltage input making them ideal for applications

where adjustments start at a nominal voltage.

ꢀ Replaces 8 Potentiometers

ꢀ Standard 3-Wire Serial Interface

ꢀ Single-Supply Operation: +3 to +5V

ꢀ Mid-Scale Reset Pin (AS1504)

ꢀ Separate VREFL Range Setting (AS1505)

ꢀ Shutdown Mode: ≤25µW (IDD and IREF)

ꢀ Power-On Reset

Functionality

Mid-Scale Reset Pin

Separate VREFL Range Settings

The devices feature a low-power shutdown reference

input current (5µA) that enables the devices to maintain

individual DAC latch settings during shutdown until nor-

mal operation is resumed.

ꢀ 16-pin SOIC-150 Package

The devices are controlled via a standard 3-wire serial

interface. Data is shifted into the DACs via the internal

serial-to-parallel shift register.

3 Applications

The AS1504/AS1505 are available in a 16-pin SOIC-150

package.

The devices are ideal for video amplifier gain control,

video equipment voltage-controlled frequencies and

bandwidths, CRT display geometric corrections and

automatic adjustments, or any other space-limited DAC

application with low power-consumption requirements.
