What are the key features of POPA2189IDR?
- Zero-drift architecture maintains input offset voltage below 8 µV over the full temperature range, eliminating drift errors in precision DC measurements
- 14 MHz gain-bandwidth product enables fast signal processing in multiplexed sensor acquisition systems with minimal bandwidth penalty
- 120 dB minimum CMRR (168 dB typical) rejects common-mode noise in differential signal chains and instrumentation front-ends
- Rail-to-rail output swing and CMOS input stage allow single-supply operation down to low voltages while preserving full dynamic range
What is POPA2189IDR used for?
The POPA2189IDR excels in precision data acquisition front-ends where low offset voltage and zero drift are critical, such as thermocouple amplifiers, strain gauge bridges, and 24-bit ADC driver circuits. Its 14 MHz bandwidth and MUX-friendly input make it ideal for multiplexed medical instrumentation, portable analytical equipment, and industrial sensor conditioning modules. Battery-powered handheld meters and weigh scales also benefit from its CMOS input stage and rail-to-rail output for accurate measurement across the full supply range.

Frequently Asked Questions
How does the zero-drift architecture of the POPA2189IDR maintain accuracy across temperature?
The zero-drift chopper-stabilized architecture continuously corrects the input offset voltage, keeping it below 8 µV maximum across the entire operating temperature range. This eliminates the typical offset drift of 0.1 µV/°C seen in standard CMOS amplifiers, ensuring stable measurements in thermally variable environments such as industrial enclosures or automotive cabins.
What signal bandwidth is available for fast multiplexed sensor channels using the POPA2189IDR?
The POPA2189IDR provides a 14 MHz gain-bandwidth product, allowing unity-gain stable amplification with settling times fast enough for multiplexed 16-bit or 24-bit ADC applications. At a gain of 10, usable signal bandwidth extends to approximately 1.4 MHz, accommodating industrial sensors operating at several hundred kilohertz.
In which precision measurement circuits is the 120 dB CMRR of the POPA2189IDR most advantageous?
Bridge transducer amplifiers measuring small differential signals of 1 mV to 10 mV riding on a large common-mode voltage benefit most from the 120 dB minimum CMRR (168 dB typical). The high rejection keeps common-mode noise contributions below 1 µV even with 1 V of supply-rail ripple, which is essential for load cells and pressure sensors in noisy industrial environments.
Can the POPA2189IDR operate from a single 3.3 V supply in portable instruments?
Yes. The CMOS input stage and rail-to-rail output allow full-specification operation from a single 3.3 V supply. The output swings within millivolts of both rails, preserving the full 3.3 V dynamic range for 16-bit ADC inputs. Quiescent current is low enough for battery-powered handheld meters requiring extended runtime.
