Applications  
The TSV6290 comes with a shutdown function.  
Battery-powered applications  
Portable devices  
The TSV6290 and TSV6291 present a high  
tolerance to ESD, sustaining 4 kV for the human  
body model.  
Signal conditioning  
Active filtering  
Additionally, the TSV6290 and TSV6291 are  
offered in SC70-5/6 and SOT23-5/6  
micropackages, with extended temperature  
ranges from -40° C to +125° C.  
Medical instrumentation  
Description  
All these features make the TSV629x ideal for  
sensor interfaces, battery-supplied and portable  
applications, as well as active filtering.  
The TSV6290 and the TSV6291 are single  
operational amplifiers with a high bandwidth while  
consuming only 29 µA. They must be used in a  
gain configuration (G<-3, G>+4).  
With a very low input bias current and low offset  
voltage (800 µV maximum for the A version), the  
TSV629x family of devices is ideal for applications  
requiring precision. The devices can operate at a  
power supply ranging from 1.5 to 5.5 V, and  
therefore suit battery-powered devices, extending  
battery life.

1. All voltage values, except differential voltage, are with respect to network ground terminal.  
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.  
3. Vcc-Vin must not exceed 6 V, Vin must not exceed 6 V.  
4. Input current must be limited by a resistor in series with the inputs.  
5. Short-circuits can cause excessive heating and destructive dissipation.  
6. Rth are typical values.  
7. 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.  
8. 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.  
9. Charged device model: all pins plus package are charged together to the specified voltage and then  
discharged directly to the ground.

Application information  
3.1  
Operating voltages  
The TSV6290 and TSV6291 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 V range and several characterization curves show the TSV629x characteristics at  
CC  
1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges  
from -40° C to +125° C.  
3.2  
Rail-to-rail input  
The TSV6290 and TSV6291 are built with two complementary PMOS and NMOS input  
differential pairs. The devices have a rail-to-rail input, and the input common-mode range is  
extended from V  
-0.1 V to V  
+0.1 V. The transition between the two pairs appears at  
CC-  
CC+  
V
-0.7 V. In the transition region, the performance of CMR, SVR, V and THD is slightly

Rail-to-rail output  
The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above  
and below the rail when connected to a 10 kΩ resistive load to V /2.  
CC  
Shutdown function (TSV6290)  
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the  
amplifier, the SHDN must be pulled down to V . When in shutdown mode, the amplifier’s  
CC-  
output is in a high impedance state. The SHDN pin must never be left floating, but tied to  
V
or V  
.

Optimization of DC and AC parameters  
These devices use an innovative approach to reduce the spread of the main DC and AC  
parameters. An internal adjustment achieves a very narrow spread of the current  
consumption (29 µA typical, min/max at 17%). Parameters linked to the current  
consumption value, such as GBP, SR and A , benefit from this narrow dispersion.  
Vd  
3.6  
Driving resistive and capacitive loads  
These products are micropower, low-voltage operational amplifiers optimized to drive rather  
large resistive loads, above 5 kΩ. For lower resistive loads, the THD level may significantly  
increase.  
The amplifiers have a relatively low internal compensation capacitor, making them very fast  
while consuming very little. They are ideal when used in a non-inverting configuration or in  
an inverting configuration in the following conditions.  
IGainI 3 in an inverting configuration (CL = 20 pF, RL = 100 kΩ) or IgainI 10  
(CL = 100 pF, RL = 100 kΩ)  
Gain +4 in a non-inverting configuration (CL = 20 pF, RL = 100 kΩ) or gain +11  
(CL = 100 pF, RL= 100 kΩ)  
As these operational amplifiers are not unity gain stable, for a low closed-loop gain it is  
recommended to use the TSV62x (29 µA, 420 kHz) or TSV63x (60 µA, 880 kHz) which are  
unity gain stable.

PCB layouts  
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible  
to the power supply pins.  
Macromodel  
An accurate macromodel of the TSV6290 and TSV6291 is available on STMicroelectronics’  
web site at www.st.com. This model is a trade-off between accuracy and complexity (that is,  
time simulation) of the TSV629x operational amplifiers. It emulates the nominal  
performances of a typical device within the specified operating conditions mentioned in the  
datasheet. It helps to validate a design approach and to select the right operational  
amplifier, but it does not replace on-board measurements.
