TPC116S8-TR

Digital To Analog Converters Overview

The TPC116S8-TR is an octal, 16-bit digital-to-analog converter (DAC) manufactured by 3PEAK. It features buffered voltage outputs with rail-to-rail operation and a low power consumption of 1.5 mA typical at 5 V. The device accepts a supply voltage range of 2.7 V to 5.5 V and utilizes a high-resistance external reference input. It incorporates a segmented resistor string architecture ensuring monotonicity without missing codes. The unit includes a power-on reset circuit that forces DAC outputs to zero volts upon startup. It operates within an extended industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '-TR' corresponds to the Tape and Reel packaging format containing 3,000 units per reel. Confirm the package type matches the TSSOP16 outline dimensions provided in the datasheet. Ensure the required operating temperature range aligns with the specified -40°C to +125°C industrial grade. Check for RoHS compliance status as defined by the manufacturer's 'Green' designation.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. The 16-bit resolution suits applications demanding high precision, such as instrumentation. Consider the 333 kΩ reference input impedance for low-power reference sourcing. Verify that the 3-wire serial interface timing requirements fit the host microcontroller's capabilities. Evaluate thermal dissipation if operating near maximum junction temperatures.

Digital To Analog Converters Part Context

The TPC116S8-TR belongs to the TPC11xS8 family of octal DACs. It is pin-compatible and software-compatible with the 12-bit TPC112S8 variant. Both devices share identical pinouts and serial protocols, allowing for design flexibility between resolution requirements. The series is designed to replace legacy multi-channel DAC solutions with lower power consumption and higher integration.

Digital To Analog Converters Replacement Considerations

The TPC112S8-TR serves as a direct pin-compatible alternative offering 12-bit resolution. For single-channel applications, the TPC116S1 provides similar specifications in an MSOP-8 package. Designers replacing other brands should verify register compatibility and serial interface timing constraints against the original component datasheet.

Digital To Analog Converters FAQ

How does the device handle digital noise feedthrough?

The TPC116S8 minimizes digital noise feedthrough by powering down the SCLK and DIN input buffers immediately after the completion of each data frame transmission.

What is the function of the CLR pin?

The CLR pin is an active-low input that clears the DAC register and resets all DAC outputs to zero volts when driven low.

Can the outputs drive capacitive loads directly?

Yes, the device can drive capacitive loads up to 0.1 nF with zero series resistance, or up to 15 μF if a 1 kΩ series resistor is used.
