New micropower op-amps
Zero trade-offs
TSV6x family delivers the best power-to-speed ratio

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 configurations for stability reasons.
They keep the same advantages as the TSV6x families: precision, low supply voltage, low input currents, as well as tiny
packages.
Key features and benefits
Features
Benefits
Ultra low supply voltage: 5.5 V down to 1.5 V
Ideal for battery-powered devices, extends battery life
Large offer - 6 ranges of power/speed:
From 10 µA/450 kHz up to 60 µA/2.4 MHz
High merit factor extends battery-life
Standby current: 5 nA typ
Significantly reduces consumption when not in use, thus extends
battery life
Very low input offset voltage:
Down to 500 µV max
Good precision for small signal conditioning
Low input bias current: 1 pA typ
Ideal for high impedance sensors
Tiny packages:
SC70-5/6, SOT23-5/6/8, MSO8/10
Board space saving
High ESD tolerance (≥4 kV HBM)
High EMI rejection ratio
Design robustness, high reliability
