AS1504, AS1505
Octal 8-Bit Programmable Low-Power DACs with
Shutdown and Mid-Scale Reset
1 General Description
Data Sheet
www.austriamicrosystems.com
Revision 1.0
1 - 17
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.
Table 1. Standard Products
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.
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.
The AS1504/AS1505 are available in a 16-pin SOIC-150
package.
