Key Features
- Wide 36 V supply voltage range with rail-to-rail output swing enabling direct interface with high-voltage sensor and actuator signals without additional level shifting
- 130 dB typical CMRR (100 dB minimum) ensuring excellent rejection of power-supply noise and common-mode interference in precision measurement circuits
- Low-power consumption with 1.7 MHz gain-bandwidth product balancing signal processing speed with battery life in portable and IoT applications
- Compact 5-pin SOT-23 package minimizing board footprint for space-constrained designs in wearables, sensors, and industrial transmitters
Applications
TSB621ILT is well-suited for 4-20 mA industrial loop transmitters, battery-powered sensor nodes, and process control signal conditioning where its 36 V supply range and rail-to-rail output accommodate wide dynamic range measurements. The 1.7 MHz bandwidth and 130 dB CMRR make it effective for active filter stages in audio and vibration monitoring equipment. Its tiny SOT-23 footprint and low quiescent current are valued in portable medical devices and wearable sensor front ends.

Frequently Asked Questions
What supply voltage range does TSB621ILT support and how does this help in industrial 24 V system designs?
TSB621ILT operates from a supply voltage up to 36 V, which directly accommodates 24 V industrial rail supplies (with ±12 V split rails or a single 24 V supply) without requiring a separate regulator, making it a natural fit for 4-20 mA loop transmitters, PLCs, and industrial sensor conditioners running from standard 24 V industrial power buses.
What is the gain-bandwidth product of TSB621ILT and which filter or amplifier stages benefit from its 1.7 MHz bandwidth?
TSB621ILT has a gain-bandwidth product of 1.7 MHz, which supports closed-loop gains up to 17x at 100 kHz or unity gain at 1.7 MHz, making it effective for anti-aliasing filters ahead of 16-bit ADCs, active low-pass filters in audio processing, and signal conditioning stages for vibration sensors and strain gauges.
How does the 130 dB CMRR of TSB621ILT benefit a differential temperature measurement bridge circuit?
With a typical CMRR of 130 dB, TSB621ILT rejects common-mode voltages (such as ground noise or supply ripple shared by both bridge legs) by a factor of over 3,000,000:1, allowing the amplifier to accurately amplify millivolt-level differential signals from a Wheatstone bridge thermistor or RTD circuit even when 50 Hz or 60 Hz interference is present on the measurement lines.
What is the maximum input offset voltage of TSB621ILT and how does it affect accuracy in a unity-gain buffer application?
TSB621ILT has a maximum input offset voltage of 1600 µV (1.6 mV) at 25°C, which translates directly to a DC accuracy error of 1.6 mV at unity gain; this is acceptable for most sensor buffering applications but should be budgeted against the full-scale range when using a 12-bit ADC with less than 5 V full-scale to avoid exceeding 0.03% offset error.
