What are the key features of TS3325AQPR?
- 2.5 V high-precision series voltage reference with tight initial accuracy for ADC and DAC reference rail applications
- Micropower quiescent current consumption enabling always-on voltage reference use in battery-operated and energy-harvesting designs
- 5 mA maximum output current sufficient to drive multiple ADC reference inputs simultaneously on a shared reference bus
- Compact 8-pin QFN package minimizing PCB area in precision measurement and portable instrumentation designs
What is TS3325AQPR used for?
TS3325AQPR is used as a stable 2.5 V reference voltage source in precision analog-to-digital and digital-to-analog converter circuits where initial accuracy and low temperature drift are critical. Its micropower consumption makes it suitable for battery-powered instruments, wearables, and IoT sensor nodes that require an always-on voltage reference without significant standby current drain. The device also serves in calibration circuits, signal chain front-ends, and data acquisition systems where a clean, low-noise 2.5 V reference prevents measurement error accumulation over time.

Frequently Asked Questions
What is the output voltage and maximum output current of TS3325AQPR?
TS3325AQPR provides a 2.5 V series voltage reference output with a maximum output current of 5 mA. The 5 mA drive capability is sufficient to supply the reference input of multiple 16-bit or 24-bit ADCs on a shared reference node, making it practical for multi-channel precision data acquisition systems without additional buffer amplifiers.
Which battery-powered measurement designs benefit most from TS3325AQPR's micropower consumption at 2.5 V?
Portable multimeters, wearable biosensors, and industrial field transmitters running from 3 V coin cells or small Li-ion packs benefit most because the micropower quiescent current of TS3325AQPR extends battery life compared to standard references drawing hundreds of microamps. A 2.5 V precision reference that consumes only a few microamps allows the host MCU to enter deep sleep while keeping ADC calibration active, reducing average system current below 50 µA in many designs.
How does the 8-pin QFN package of TS3325AQPR compare in board area to a SOT-23 voltage reference?
The 8-pin QFN package of TS3325AQPR occupies approximately 2 mm x 2 mm of PCB footprint, which is comparable to a SOT-23 at 1.6 mm x 2.9 mm but adds extra pins for better thermal dissipation and noise bypass capacitor placement. The QFN form factor allows tighter decoupling of the 2.5 V reference output by placing a 100 nF ceramic capacitor directly beneath the package pad, improving noise rejection at frequencies above 1 MHz.
When is TS3325AQPR preferred over a bandgap reference built into an ADC for precision signal chain design?
TS3325AQPR is preferred when the application demands a dedicated 2.5 V reference shared across multiple ADC or DAC channels, or when the integrated ADC reference has insufficient drive current below 1 mA for the load. An external precision reference like TS3325AQPR with 5 mA output also provides better isolation from digital supply noise and allows independent trimming of the reference voltage to compensate for PCB-level offset errors in a multi-channel 16-bit or higher resolution measurement system.
