What are the key features of TPL0501-100RSER?
- 256 wiper positions over a 100 kΩ full-scale resistance providing approximately 392 Ω resolution per step for fine-grained digital trimming
- SPI-compatible 3-wire serial interface enabling direct connection to microcontroller SPI buses at standard 3.3 V or 5 V logic
- Single-channel architecture in a compact 8-pin WSON package for minimal board footprint in space-constrained analog trim circuits
- Non-volatile wiper position option retains calibration setting through power cycles without external EEPROM
What is TPL0501-100RSER used for?
The TPL0501-100RSER enables software-adjustable gain, offset, and bias trimming in precision instrumentation, sensor calibration circuits, and programmable filter networks controlled via microcontroller SPI buses. Its 256-step 100 kΩ range suits feedback resistor adjustment in op-amp circuits and voltage-divider calibration for ADC reference networks where mechanical potentiometers are impractical. The digital interface allows automated production calibration routines to set and verify the wiper position in manufacturing test fixtures without manual intervention.

Frequently Asked Questions
With 256 taps over 100 kΩ, what resistance step resolution does TPL0501-100RSER provide per LSB?
Dividing the 100 kΩ end-to-end resistance across 256 positions yields approximately 392 Ω per step, enabling fine-grained gain adjustment in amplifier feedback networks where ±200 Ω accuracy is sufficient for 8-bit calibration precision.
How does the 3-wire SPI interface of TPL0501-100RSER simplify integration with a low-pin-count microcontroller?
The 3-wire serial interface uses CS, CLK, and SDI lines, requiring only 3 GPIO pins on the host MCU — compatible with hardware SPI peripherals on most 8-bit and 32-bit microcontrollers at clock rates up to several MHz without additional level-shifting at 3.3 V logic.
In a programmable low-pass filter circuit, how does the 250 Hz bandwidth of TPL0501-100RSER limit the usable signal frequency range?
The 250 Hz nominal bandwidth of the wiper means signal frequencies above approximately 250 Hz experience increasing attenuation through the wiper resistance, restricting the TPL0501-100RSER to DC or sub-audio frequency trimming applications rather than RF or high-frequency signal switching.
For automated PCB calibration, how does replacing a mechanical trimmer with TPL0501-100RSER reduce test time?
A firmware routine can write a new 8-bit wiper code over SPI in under 1 µs per command, iterate through all 256 positions while reading a sensor output, and lock the optimal code — replacing a manual screwdriver adjustment that might take 30 seconds to 2 minutes per board during production test.
