Texas Instruments TPL0202-10MRTER

Overview

TPL0202-10MRTER from Texas Instruments is a dual-channel, 256-tap digital potentiometer with non-volatile EEPROM storage, 10-kΩ end-to-end resistance, ±1 LSB INL, and SPI serial interface. It operates from 2.7 V to 5.5 V across –40°C to +105°C and serves as a precision replacement for mechanical potentiometers in calibration and trimming circuits.

For engineers reviewing the TPL0202-10MRTER datasheet, TPL0202-10MRTER pinout, TPL0202-10MRTER application, or TPL0202-10MRTER equivalent, key selection criteria include wiper position retention on power-up, channel-to-channel matching (±2 LSB), ratiometric temperature coefficient (12 ppm/°C), and fast power-up response (<100 µs).

Technical Context

The TPL0202-10MRTER integrates two independent linear-taper digital potentiometers, each configurable as either a three-terminal voltage divider or two-terminal rheostat. Its SPI interface supports up to 5 MHz clock frequency with defined setup/hold timing (tDS = 50 ns, tCSH = 0 ns) and active-low chip select.

Non-volatile memory stores wiper positions with 10,000 write cycles at 25°C and 20-year data retention at 105°C. Wiper registers load automatically at power-on when VDD exceeds 2 V, completing recall within 35–100 µs.

FAQ

What is the end-to-end resistance tolerance of the TPL0202-10MRTER?

The TPL0202-10MRTER has a nominal end-to-end resistance of 10 kΩ with a tolerance of ±20%, specified as 8 kΩ to 12 kΩ under test conditions (VL = VDD/2, IHL = 100 µA, code = 0x80). This tolerance applies to both channels A and B independently and remains stable across the full operating temperature range.

Does the TPL0202-10MRTER support true voltage-divider operation with bipolar signals?

Yes - the TPL0202-10MRTER allows H and L terminals to operate at any voltage between GND and VDD, with no polarity restriction. The wiper (W) terminal tracks proportionally between them, enabling true ratiometric voltage division even when VL > VH, as long as both remain within the 0 V to VDD range.

How many times can the non-volatile memory in the TPL0202-10MRTER be written?

The EEPROM in the TPL0202-10MRTER supports 10,000 write cycles at 25°C and 1,000 cycles at 105°C. Each write operation stores both channel wiper positions simultaneously. Data retention is rated for 20 years at 105°C or 100 years at 85°C, per TI's characterization.

Can both potentiometer channels of the TPL0202-10MRTER operate in different modes simultaneously?

Yes - the TPL0202-10MRTER allows independent configuration: Pot A may operate in voltage-divider mode while Pot B functions as a rheostat, or vice versa. Mode selection is determined by external connections (e.g., floating unused terminal), not internal register settings.

What is the maximum SPI clock frequency supported by the TPL0202-10MRTER?

The TPL0202-10MRTER supports an SPI clock frequency up to 5 MHz across its full operating temperature and voltage range. Timing parameters including tSCH (80 ns min high time) and tSCL (80 ns min low time) are guaranteed per the datasheet's Section 6.7.
