Description

The 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.

Application information TSV620, TSV620A, TSV621, TSV621A 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 1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges from -40° C to +125° C. 3.

TSV620, TSV620A, TSV621, TSV621A 3.4 Application information Shutdown function (TSV620) The operational amplifier is enabled when the SHDN pin is pulled high. To disable the amplifier, the SHDN pin must be pulled down to VCC-. When in shutdown mode, the amplifier output is in a high impedance state. The SHDN pin must never be left floating but tied to VCC+ or VCC-. The turn-on and turn-off times are calculated for an output variation of ±200 mV (Figure 16 and Figure 17 show the test configurations).

Application information 3.5 TSV620, TSV620A, TSV621, TSV621A Optimization of DC and AC parameters This device uses an innovative approach to reduce the spread of the main DC and AC parameters. An internal adjustment achieves a very narrow spread of current consumption (29 µA typical, min/max at ±17%). Parameters linked to the current consumption value, such as GBP, SR and AVd benefit from this narrow dispersion. All parts present a similar speed and the same behavior in terms of stability.
