Features and Benefits
- Smallest Pin-Compatible Single DACs:
- LTC2601: 16 Bits
- LTC2611: 14 Bits
- LTC2621: 12 Bits
- Guaranteed Monotonic Over Temperature
- Wide 2.5V to 5.5V Supply Range
- Low Power Operation: 300µA at 3V
- Power Down to 1µA, Max
- High Rail-to-Rail Output Drive (±15mA, Min)
- Double-Buffered Data Latches
- Asynchronous DAC Update Pin
- LTC2601-1/LTC2611-1/LTC2621-1: Power-On Reset to Midscale
- Tiny (3mm x 3mm) 10-Lead DFN Package
The LTC2601/LTC2611/LTC2621 are single 16-, 14- and 12-bit, 2.5V-to-5.5V rail-to-rail voltage output DACs in a 10-lead DFN package. They have built-in high performance output buffers and are guaranteed monotonic.
These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive and load regulation in single-supply, voltage-output DACs.
The parts use a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisy-chain capability, hardware CLR and asynchronous DAC update (LDAC) pins are included.
The LTC2601/LTC2611/LTC2621 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2601-1/LTC2611-1/LTC2621-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place.

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.
