Product details
Overview
TPL0102-100QPWREP from Texas Instruments is a dual-channel, 256-tap digital potentiometer with non-volatile EEPROM memory, 100-kΩ end-to-end resistance, ±0.5 LSB INL, and I²C-compatible serial interface. It operates from 2.7 V to 5.5 V single supply or ±2.25 V to ±2.75 V dual supply, and is qualified for extended temperature (–40°C to 125°C) in defense, aerospace, and medical applications.
For engineers reviewing the TPL0102-100QPWREP datasheet, TPL0102-100QPWREP pinout, TPL0102-100QPWREP application, or TPL0102-100QPWREP equivalent, this device supports precision analog trimming in harsh-environment systems where power-cycle wiper recall, low drift, and compact 2-mm × 2-mm TSSOP packaging are critical.
Technical Context
The TPL0102-100QPWREP implements two independent linear-taper digital potentiometers, each configurable as a three-terminal voltage divider or two-terminal rheostat. Wiper position is controlled via 8-bit WR registers accessed through standard-mode (100 kHz) or fast-mode (400 kHz) I²C.
Non-volatile EEPROM stores wiper settings across power cycles, with recall completed within 35–100 µs after VDD exceeds 2 V. Ratiometric temperature coefficient is 4 ppm/°C, and channel-to-channel resistance match is 0.1%, enabling matched gain/offset control in dual-path signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 100 kΩ (80–120 kΩ tolerance); defines full-scale analog range for gain/attenuation circuits |
| Resolution | 256 taps (8-bit); enables 0.39% step resolution in voltage-divider mode |
| INL / DNL | ±0.5 LSB / ±0.25 LSB; ensures monotonicity and accurate setpoint calibration |

| VDD, VSS | Positive/negative supply | Supports single-supply (VSS = GND) or true dual-supply (VSS negative) operation |
| GND | Ground reference | System ground connection; separate from VSS when used in dual-supply configuration |
Key Features
| Feature | Design Value |
|---|---|
| Non-volatile wiper storage | EEPROM retains last wiper position across power cycles; 1000 write cycles, 100,000-hour retention |
| Ratiometric tempco | 4 ppm/°C ensures stable voltage-divider ratio over temperature - critical for precision references |

| Dual independent channels | Two fully isolated 100-kΩ potentiometers enable simultaneous gain/offset trim in differential or dual-path systems |
| Low wiper resistance | 25 Ω typical (max 120 Ω) minimizes insertion loss and loading error in high-impedance feedback networks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5172BRUZ10 | Single-supply only (2.7–5.5 V); no dual-supply support; 10-kΩ end-to-end resistance; SPI interface | Lacks ±2.25 V dual-supply capability and I²C compatibility; unsuitable for bipolar signal path trimming | Select when SPI interface and lower resistance are preferred; verify layout compatibility with 14-TSSOP footprint |
| MCP45HV51-103E/ST | High-voltage tolerant (up to ±36 V across H-L); 100-kΩ; I²C; but only 125°C max junction temperature (no extended temp grade) | No Q-grade qualification; not rated for defense/aerospace use; lacks 100,000-hour EEPROM retention spec | Choose for high-voltage analog front-ends where extended temperature and long-term memory retention are not required |
Compared with AD5172BRUZ10 and MCP45HV51-103E/ST, the TPL0102-100QPWREP uniquely combines dual-supply operation, extended temperature qualification, and guaranteed EEPROM endurance - making it the only option for recalibratable, high-reliability bipolar analog systems in harsh environments.

FAQ
What is the end-to-end resistance tolerance of the TPL0102-100QPWREP?
The TPL0102-100QPWREP has a nominal end-to-end resistance of 100 kΩ with a tolerance of ±20%, specified as 80 kΩ minimum to 120 kΩ maximum across temperature and process variation. This tolerance applies to the HA–LA and HB–LB terminals in voltage-divider mode and is confirmed in Section 7.5 of the SLIS149 datasheet.
Does the TPL0102-100QPWREP support dual-supply operation?
Yes, the TPL0102-100QPWREP supports true dual-supply operation from ±2.25 V to ±2.75 V, allowing H and L pins to straddle ground (e.g., HA = +2.5 V, LA = –2.5 V). This enables bipolar signal path trimming in instrumentation and medical amplifier designs, as verified in Section 7.3 Recommended Operating Conditions.
How many I²C addresses can be assigned to the TPL0102-100QPWREP?
The TPL0102-100QPWREP supports eight unique I²C addresses via hardware-configurable A0, A1, and A2 pins. With base address 0x50, combinations yield addresses 0x50–0x57. This allows up to eight devices on a single I²C bus without address conflict, as documented in Section 8.3.1.3 and Figure 13.
What is the wiper resistance specification for the TPL0102-100QPWREP?
The TPL0102-100QPWREP specifies wiper resistance (RW) as 25 Ω typical, with a maximum of 120 Ω over temperature and process. This low on-resistance minimizes gain error in op-amp feedback networks and ensures predictable loading in precision voltage-divider configurations per Section 7.5 Electrical Characteristics.
Is the TPL0102-100QPWREP qualified for extended temperature operation?
Yes, the TPL0102-100QPWREP is explicitly qualified for operation from –40°C to 125°C ambient temperature, with controlled baseline, extended product life cycle, and traceability features required for defense, aerospace, and medical applications - as stated in the Device Information table and Section 3 Description.
