TPC116S1-VR

Digital To Analog Converters Overview

The TPC116S1-VR is a single-channel, 16-bit digital-to-analog converter (DAC) from 3PEAK. It features buffered voltage output with rail-to-rail operation and guaranteed monotonicity by design. The device operates on a supply voltage range of 2.7 V to 5.5 V and consumes 90 μA typically at 5 V. It utilizes a high-resistance external reference input (333 kΩ typical) for low system power consumption. Key electrical parameters include ±8 LSB maximum differential nonlinearity (DNL), ±16 LSB maximum integral nonlinearity (INL), and a glitch energy of 2 nV·s. The part includes a power-on reset circuit ensuring the output powers up to 0 V.

Digital To Analog Converters Feature Summary

• 16-bit resolution with segmented resistor string architecture
• Buffered rail-to-rail output amplifier with 0.1 Ω DC output impedance
• Power-on reset (POR) ensures DAC output initializes to 0 V
• Software-selectable power-down modes reducing current to 400 nA at 5 V

Digital To Analog Converters Applications

• Gain and offset adjustment circuits
• Process control and servo loops
• Portable instrumentation
• Programmable voltage and current sources
• Automatic test equipment

Digital To Analog Converters Procurement Notes

Verify the package marking 'C116S1' to confirm the specific 16-bit variant within the TPC11xS1 family. Ensure the application supports the MSOP8 thermal characteristics, as the junction-to-ambient thermal resistance is 210 °C/W. Confirm that the external reference voltage applied to the VREF pin falls within the specified range of +2 V to VDD to maintain proper operation.

Digital To Analog Converters Selection Notes

Select the TPC116S1-VR when 16-bit accuracy is required alongside low power consumption. This component is a drop-in replacement for DAC8551 and DAC7512 in terms of pinout and software compatibility. Consider the 24-bit serial interface requirement for data loading, which differs from the 16-bit interfaces used by the lower-resolution TPC112S1 and TPC114S1 variants.

Digital To Analog Converters Part Context

The TPC116S1-VR belongs to the TPC11xS1 series, which also includes the 14-bit TPC114S1 and 12-bit TPC112S1. These devices share identical pinouts, packaging, and control logic, allowing for flexible design upgrades without PCB layout changes. The '-VR' suffix indicates the device is supplied in tape and reel format, suitable for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

Publicly documented drop-in compatible replacements include the DAC8551 and DAC7512. Designers should verify that the substitute components meet the specific glitch energy and settling time requirements of the original design, as these dynamic performance metrics may vary between manufacturers.
