Product catalog summary

Introduction
STMicroelectronics has introduced three new micropower op-amp families: TSV619x, TSV629x, and TSV639x. These are designed for low-voltage, battery-powered applications, offering improved power-to-speed ratios compared to previous TSV6x families.

Specifications and Features

Ultra Low Supply Voltage: Operates from 1.5 V to 5.5 V, ideal for extending battery life in portable devices.
Power/Speed Ranges: Six ranges from 10 µA/450 kHz to 60 µA/2.4 MHz, providing flexibility in power and speed requirements.
Standby Current: 5 nA typical, significantly reducing power consumption when not in use.
Precision: Low input offset voltage down to 500 µV max, suitable for small signal conditioning.
Input Bias Current: 1 pA typical, ideal for high impedance sensors.
Package Options: Available in tiny packages like SC70-5/6, SOT23-5/6/8, MSO8/10, saving board space.
Robustness: High ESD tolerance (≥4 kV HBM) and high EMI rejection ratio ensure design reliability.

Applications

Battery-powered devices
Signal conditioning and filtering
Medical handheld devices
Smoke detectors
Low-side current sensing
Photodiode pre-amplification

Performance Comparison
The TSV6x and TSV6x9x families offer complementary features to meet diverse application needs. The TSV62x series is noted for its stable supply current across varying supply voltages and temperatures.

Technical Data Summary
The document includes detailed tables comparing various op-amp models, highlighting parameters such as supply voltage, input offset voltage, input bias current, supply current per operator, gain-bandwidth product (GBP), slew rate, stability gain, and equivalent input noise voltage. These specifications are crucial for selecting the appropriate op-amp for specific applications.

Conclusion
The TSV6x family of op-amps by STMicroelectronics provides enhanced performance for low-voltage applications, offering significant power savings and precision, making them suitable for a wide range of battery-powered and portable devices.

Enlarged TSV6x family for extended battery life and high accuracy at low voltage STMicroelectronics has recently introduced three new micropower op-amp families for power saving in low-voltage applications. The TSV619x, TSV629x and TSV639x, based on previous TSV6x families, further reduce power consumption for handheld, battery-supplied applications. They offer an outstanding merit factor. For the same consumption as the TSV6x, they offer a gain-bandwidth product increased by a factor of 3 and have twice the slew rate value. They are intended for non-inverting (G ≥ +4) or inverting (G ≤ -3) gain...
