DAC7311IDCKR

Digital To Analog Converters Overview

The DAC7311IDCKR is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates on a supply voltage range of 2V to 5.5V and features a resistor-string architecture. The device supports a sampling rate of 83 kS/s with a typical settling time of 6 µs. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Key performance metrics include a gain error of 0.15% FSR, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±0.2 LSB. Power consumption is 140 µW at 2.5V, rising to 180 µA operating current. It functions within an industrial temperature range of -40°C to +125°C in a compact SC-70-6 surface-mount package.

Digital To Analog Converters Feature Summary

• Monotonic design ensures stable operation without missing codes across the full input range.
• Integrated power-on reset circuit maintains the output at 0V until valid data is written.
• Pin-compatible with 8-bit, 10-bit, 14-bit, and 16-bit variants for simplified design upgrades.
• Low-power shutdown mode reduces current draw to 0.1 µA at 2.0V.

Digital To Analog Converters Applications

• Portable battery-powered instrumentation
• Programmable voltage references
• Gain control stages in signal processing chains

Digital To Analog Converters Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging when ordering. Confirm the 'I' designation matches the required -40°C to +125°C industrial temperature grade. Ensure the SC-70-6 footprint aligns with the target PCB layout. Cross-reference the specific datasheet revision for any recent pinning or electrical specification updates.

Digital To Analog Converters Selection Notes

Select this component for applications requiring 12-bit resolution in a minimal footprint. It serves as a direct upgrade path from the 8-bit DAC5311 and 10-bit DAC6311 due to identical pinouts. Consider the DAC8311 if higher 14-bit precision is needed without changing the board layout. Evaluate power constraints against the 140 µW active consumption.

Digital To Analog Converters Part Context

This part belongs to the DACx311 family of single-channel DACs. The series includes resolutions ranging from 8 to 16 bits, all sharing the same SC-70-6 package and pin configuration. This design allows engineers to scale resolution requirements during product development without redesigning the hardware interface.

Digital To Analog Converters FAQ

Does the DAC7311 support differential outputs?

No, the DAC7311 provides only a single-ended buffered voltage output.

What is the maximum clock speed for the serial interface?

The multi-function 3-wire serial interface supports clock rates up to 50 MHz.

How does the device handle power-up states?

An integrated power-on reset (POR) circuit holds the DAC output at 0V until valid data is written to the device.
