Typical Applications
PGA207UA/1K is suitable for 6 applications: Multiplexed Data Acquisition Front End, Industrial Sensor Signal Conditioning, Test and Measurement Instrumentation, Photodiode and Transimpedance Front Ends, Medical Diagnostic Signal Acquisition, Audio and Acoustic Measurement.
Multiplexed Data Acquisition Front End
The PGA207UA/1K is purpose-built for multiplexed data acquisition, where many sensor channels of differing amplitude share one ADC. Its fast settling to 0.01% allows the mux to switch channels without long dead time, directly increasing samples-per-second. The FET input stage draws only 100 pA max bias current, so it does not load high-impedance sources after channel switching. Place the PGA between the analog multiplexer and the ADC driver stage with gains of 1, 2, 5, or 10 selected dynamically per channel via the two TTL address lines, letting a 10 mV thermocouple and a 5 V strain-gage bridge share one converter. Unlike fixed-gain instrumentation amplifiers, no resistor changes or multiple amp types are needed, simplifying BOM and calibration.

Industrial Sensor Signal Conditioning
In industrial environments, transducers such as pressure bridges, RTDs, and current-shunt signals span millivolts to volts. The PGA207UA/1K covers this spread with its digitally selected 1-10x gains while its laser-trimmed 1.5 mV max offset avoids calibration overhead in production. The +/-40V internal input protection, functional even with supplies off, guards against wiring faults and hot-plug events common on factory floors. Operated from +/-12V or +/-15V industrial analog rails, the device drives ADC or PLC input stages through short, guarded runs. Designers should series-limit fault current beyond the protection rating and route digital gain-select lines away from input traces so PLC switching noise does not degrade the microvolt-level offset performance the laser trim provides.
Recommended
Test and Measurement Instrumentation
Bench instruments, DAQ cards, and automated test equipment benefit from the PGA207UA/1K's combination of 5 MHz bandwidth and programmable gain, allowing one analog front end to serve oscilloscope-class and DMM-class input ranges. The 25 V/us slew rate preserves fast edges at 10x gain, while FET 100 pA inputs prevent loading on high-impedance probes. In a typical instrument chain, range-selection logic drives the two gain address lines as the user changes vertical scale, and the fast settling ensures the display updates without transient artifacts. Because gains are laser-trimmed, range-to-range gain consistency is maintained without per-unit adjustment, a key requirement for instrument calibration cycles and multi-channel phase-matched acquisition systems.
Recommended
Photodiode and Transimpedance Front Ends
Optical receivers with photodiodes spanning weak and strong illumination require variable transimpedance gain; placing the PGA207UA/1K after a fixed TIA provides coarse programmable gain without adding input noise to the first stage. The FET input bias of 100 pA max prevents the PGA from loading the TIA output node, and its 5 MHz bandwidth supports kHz-to-MHz optical pulse trains. Because the photodiode signal can saturate under bright conditions, the +/-40V input protection adds robustness during probing and maintenance. Designers should select gain adaptively via the TTL address lines based on an ADC range check, keeping the signal within converter dynamic range while preserving resolution on weak signals.
Recommended
Medical Diagnostic Signal Acquisition
Medical instrumentation such as patient-monitoring front ends and diagnostic analyzers handles electrode and sensor signals that vary widely between patients and sensors. The PGA207UA/1K's high-impedance FET inputs (100 pA max) minimize loading and motion artifacts on bioelectric or chemical sensor outputs, and digital gain switching lets one hardware design adapt to multiple probe types. Laser-trimmed offset of 1.5 mV max simplifies system calibration required by medical device QA. Note that for direct patient-connected circuits, additional isolation and safety compliance layers are mandatory upstream and downstream; the PGA serves in the isolated analog section where its +/-40V protection and stable gain accuracy support reliable, repeatable measurements across gain ranges.
Recommended
Audio and Acoustic Measurement
Acoustic analyzers and audio test sets encounter microphone and hydrophone outputs spanning microvolts to volts. The PGA207UA/1K's programmable 1-10x gain accommodates this dynamic range ahead of a fixed-gain ADC chain, while its 5 MHz bandwidth vastly exceeds audio needs, ensuring flat response and negligible phase shift in the 20 Hz-20 kHz band. The FET input's 100 pA bias avoids DC offsets across high-value mic coupling networks, and laser trim keeps gain stepping accurate for SPL calibration. The fast 0.01% settling supports gated burst measurements and transient acoustic tests. Designers should minimize digital noise coupling from gain-select lines to preserve low-noise performance in high-gain settings.

Key Differentiators
- Low-gain, wide-dynamic-range gain set (vs PGA204AU)
- Identical gain set to PGA205AU with direct interchangeability (vs PGA205AU)
- Digitally programmed gain with no external resistors (vs discrete PGA solutions)
Design Notes
Place 0.1uF ceramic decoupling capacitors within 2 mm of both supply pins (V+ and V-) and add 10uF bulk capacitance per rail on the board. The PGA207UA/1K is a high-speed (5 MHz) part, so an uninterrupted ground plane under the SOIC-16 footprint is essential. Keep the two digital gain-select address lines short and route them on a layer separated from the analog input traces by ground; the CMOS/TTL address inputs switch rapidly and can couple glitches into the high-impedance FET input stage during gain transitions.
The +/-40V input protection is specified in voltage, not fault current. For sustained overvoltage or hot-plug conditions in industrial systems, add series resistors (e.g., 10k) to limit fault current into the protected inputs, accepting the small noise contribution per theJohnson noise of the resistor. Also remember that settling time is specified to 0.01%: in multiplexed systems, allow the full settling interval after each mux switch or gain change before triggering the ADC, or measured accuracy will degrade, especially at the 10x gain setting where the internal stage swing is largest.
At 10x gain the PGA207UA/1K's 5 MHz bandwidth yields a closed-loop bandwidth near the part's full limit, so any source impedance mismatch or stray capacitance at the inputs can cause peaking. Keep source impedance below a few kilo-ohms or add a small compensation capacitor across the feedback path as needed. For precision DC accuracy, exploit the laser-trimmed 1.5 mV max offset but still budget for offset drift over temperature - the device is trimmed for low drift, yet systems requiring sub-millivolt accuracy over an industrial range should include a periodic zero-point calibration channel.
