TSV620, TSV620A, TSV621, TSV621ARail-to-rail input/output 29 µA 420 kHz CMOS operational amplifiers
Features Low supply voltage: 1.5 V–5.5V Rail-to-rail input and output Low input offset voltage: 800 µV max (A
version) Low power consumption: 29 µA typ Low power shutdown mode: 5nA typ (TSV620) Gain bandwidth product: 420 kHz typ Unity gain stability Micropackages: SC70-5/6, SOT23-5/6 Low input bias current: 1 pA typ Extended temperature range: -40 to +125°C 4kV HBM
Applications Battery-powered applications Portable devices Signal conditioning Active filtering Medical instrumentation
DescriptionThe TSV620 and TSV621 are single operational
amplifiers offering low voltage, low power
operation and rail-to-rail input and output.
With a very low input bias current and low offset
voltage (800 µV maximum for the A version), the
TSV62x is ideal for applications requiring
precision. The device can operate at a power
supply ranging from 1.5 to 5.5 V, and therefore
suits battery-powered devices and extends their
battery life.
This product features an excellent speed/power
consumption ratio, offering a 420 kHz gain
bandwidth while consuming only 29 µA at a
5 V supply voltage.
These operational amplifiers are unity gain stable
for capacitive loads up to 100 pF.
The device is internally adjusted to provide very
narrow dispersion of AC and DC parameters,
especially power consumption, product gain
bandwidth and slew rate.
The TSV62x presents a high tolerance to ESD,
sustaining 4 kV for the human body model.
The devices are offered in macropackages,
SC70-6 and SOT23-6 for the TSV620 and
SC70-5 and SOT23-5 for the TSV621. They are
guaranteed for industrial temperature ranges from
-40° C to +125°C.
All these features make the TSV620 and TSV621
ideal for sensor interfaces, battery-supplied and
portable applications, as well as active filtering.

Doc ID 14912 Rev 2 3/24 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings (AMR) All voltage values, except differential voltage are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. Vcc-Vin must not exceed 6V. Input current must be limited by a resistor in series with the inputs. Vcc-SHDN must not exceed 6V. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating. Machine mode: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.
10. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.

3 Application information
3.1 Operating voltages
The TSV620 and TSV621 can operate from 1.5 to 5.5 V. Their parameters are fully specified
for 1.8, 3.3 and 5 V power supplies. However, the parameters are very stable in the full VCC
range and several characterization curves show the TSV62x characteristics at 1.5V.
Additionally, the main specifications are guaranteed in extended temperature ranges from
-40° C to +125°C.
3.2 Rail-to-rail input
The TSV62x is built with two complementary PMOS and NMOS input differential pairs. The
device has a rail-to-rail input and the input common mode range is extended from
VCC- -0.1 V to VCC+ +0.1V . The transition between the two pairs appears at VCC -0.7 V. In
the transition region, the performances of CMRR, PSRR, Vio and THD are slightly degraded
(as shown in Figure 14 and Figure 15 for Vio vs. Vicm).
The device is guaranteed without phase reversal.
3.3 Rail-to-rail output
The operational amplifier’s output level can go close to the rails: 35 mV maximum above and
below the rail when connected to a 10 kΩ resistive load to VCC/2.
