1 General Description
The AS1504/AS1505 are low-power (5A @ 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. Table 1.

8 Individually-Controlled DACs 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: ≤25W (IDD and IREF) Power-On Reset 16-pin SOIC-150 Package
The devices feature a low-power shutdown reference input current (5A) 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.
3 Applications
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 sp……
