LTC1597-1ACN#PBF

Digital To Analog Converters Overview

The LTC1597-1ACN#PBF is a 16-bit multiplying digital-to-analog converter (DAC) with parallel input and current output, manufactured by Analog Devices Inc. It operates from a single 5V supply and features on-chip 4-quadrant resistors for precise bipolar operation. The device includes an internal deglitcher circuit that reduces glitch impulse to less than 2nV-s typical. An asynchronous CLR pin resets the DAC to mid-scale. Key electrical specifications include a maximum integral nonlinearity (INL) of ±0.35 LSB and differential nonlinearity (DNL) of ±0.2 LSB over the industrial temperature range. Power consumption is typically 10µW.

Digital To Analog Converters Feature Summary

• True 16-bit performance with INL/DNL accuracy within ±1 LSB over the industrial temperature range
• On-chip 4-quadrant resistors enable precise 0V to 10V, 0V to –10V, or ±10V outputs
• Asynchronous Clear (CLR) pin resets the LTC1597-1 to mid-scale code
• Low power consumption with typical supply current of 10µA

Digital To Analog Converters Applications

• Process control and industrial automation
• Direct digital waveform generation
• Software-controlled gain adjustment
• Automatic test equipment

Digital To Analog Converters Procurement Notes

Verify the component matches the specific -1 suffix designation, which indicates the asynchronous clear function resets the output to mid-scale rather than zero scale. Confirm the ACN package variant corresponds to the 28-lead narrow PDIP format suitable for through-hole mounting. Ensure the #PBF suffix confirms lead-free and RoHS compliance status as per manufacturer standards.

Digital To Analog Converters Selection Notes

Select this part when 16-bit resolution and low glitch energy are required for multiplying DAC applications. The -1 suffix is critical if the system requires a known mid-scale reset state upon power-up or clear command. Verify that the external operational amplifier selection supports the high accuracy requirements, as op amp performance significantly impacts overall system linearity and distortion metrics.

Digital To Analog Converters Part Context

This component belongs to the LTC1591/LTC1597 family of pin-compatible parallel input DACs. The LTC1597 provides 16-bit resolution compared to the 14-bit LTC1591. The -1 variant specifically modifies the clear function behavior to mid-scale. The ACN suffix denotes the commercial temperature grade (0°C to 70°C) housed in a narrow plastic dual in-line package.

Digital To Analog Converters Replacement Considerations

The LTC1591-1ACN#PBF serves as a pin-compatible alternative offering 14-bit resolution instead of 16-bit. Other members of the LTC1597 family, such as the AIG or BCN variants, provide different temperature ranges or accuracy grades but maintain functional compatibility.
