LTC1590: Dual Serial 12-Bit Multiplying DAC Data Sheet8/31/2007PDF252K
Overview
Features and Benefits
- DNL and INL Over Temperature: ±0.5LSB Max
- Gain Error: ±1LSB Max
- Low Supply Current: 10µA Max
- 4-Quadrant Multiplication
- Power-On Reset
- Asynchronous Clear Input

Product Details
The LTC1590 is a dual, serial input 12-bit multiplying digital-to-analog converter (DAC). It includes two current output multiplying CMOS DACs and an easy SPI compatible serial interface with daisy-chain output. An asynchronous CLR pin sets both DACs to zero scale.
Excellent accuracy, stability and versatility are combined with the smallest package available for a dual 12-bit multiplying DAC.
Parts are available in 16-pin PDIP and narrow SO packages and are specified over the commercial and industrial temperature ranges.
Applications
- Process Control and Industrial Automation
- Software Controlled Gain Adjustment
- Digitally Controlled Filter and Power Supplies
- Automatic Test Equipment

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
