TPC2192-WLPR

Digital To Analog Converters Overview

The TPC2192-WLPR is an 8-channel, 12-bit voltage-output digital-to-analog converter (DAC) from the TPC219 family. It features a typical integral nonlinearity (INL) of ±0.5 LSB and includes an integrated 2.5V internal reference with a temperature coefficient of 8 ppm/°C. The device supports flexible output configurations via selectable gain settings (1/2, 1, or 2), enabling full-scale output voltages of 1.25V, 2.5V, or 5V. It operates on a single analog supply (VDD: 2.7V to 5.5V) and a separate digital IO supply (VIO: 1.7V to 5.5V). Key specifications include a maximum short-circuit current of 28mA, a settling time of 6µs, and support for daisy-chain SPI communication with CRC error checking. The component is characterized for operation between -40°C and +125°C and is housed in a WLCSP 2.4x2.4-16 package.

Digital To Analog Converters Feature Summary

• High Accuracy: 12-bit resolution with typical INL of ±0.5 LSB and total unadjusted error of ±0.05% FSR.
• Integrated Reference: Built-in 2.5V reference with low drift (8 ppm/°C) and high load capability (±5 mA).
• Flexible Output: User-selectable gain (1/2, 1, 2) allows configurable full-scale outputs of 1.25V, 2.5V, or 5V.
• Robust Interface: Supports 4-wire SPI with daisy-chain operation and optional CRC-8 error checking.

Digital To Analog Converters Applications

• Industrial automation systems requiring multi-channel precision control.
• Optical networking equipment utilizing DACs for signal modulation or biasing.
• Data acquisition systems needing synchronized multi-channel voltage generation.

Digital To Analog Converters Procurement Notes

Verify that the specific order number matches the required resolution and package type. The TPC2192 denotes 12-bit resolution, while the suffix WLPR indicates the WLCSP 2.4x2.4-16 package. Confirm thermal pad connectivity requirements for the WLCSP footprint during PCB layout review.

Digital To Analog Converters Selection Notes

Select the TPC2192-WLPR when 12-bit resolution is sufficient for the application, offering cost advantages over the 16-bit TPC2190 variant within the same pin-compatible family. Ensure the system design accommodates the separate VDD and VIO supply rails. Verify that the capacitive load does not exceed stability limits (up to 2nF unloaded) without external buffering.

Digital To Analog Converters Part Context

The TPC2192-WLPR belongs to the TPC219 family, which includes pin-compatible variants with 16-bit (TPC2190) and 14-bit resolutions. This family shares identical pinouts and register structures, facilitating design upgrades or downgrades without PCB redesign. The WLCSP package provides a compact form factor suitable for space-constrained applications compared to the QFN options.

Digital To Analog Converters Replacement Considerations

Pin-compatible replacements within the TPC219 family include the TPC2190-WLPR (16-bit) and TPC2190M-WLPR (16-bit, mid-scale reset). These alternatives offer higher resolution but may require verification of software compatibility if specific resolution-dependent logic is implemented.
