Octal 8-Bit Programmable Low-Power DACs with Shutdown and Mid-Scale Reset

Data Sheet
1 General Description
2 Key Features

The AS1504/AS1505 are low-power 5µA 5V individually programmable 8-channel, 8-bit resolution digital-toanalog converters. All eight DACs share a common reference-voltage input making them ideal for applications where adjustments start at a nominal voltage.

Functionality

AS1504

Mid-Scale Reset Pin

AS1505

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 normal 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.
