TPA5521/TPA5522

3.3-V, 78-kHz, Zero-Drift, Low-Power OP Amps

Features

Description

The TPA552x is the low-power, zero-drift amplifier with

maximum 30-μV low-offset voltage and stable frequency

response for the high-precision sensing applicaiton that

also requires low standby power.

Supply Voltage: 1.7 V to 3.6 V

•

Low Power: Maximum 15 μA at 25°C

Low Offset Voltage: ±30 μV Maximum at 25°C

Zero Drift: ±0.025 µV/°C

•

The TPA552x devices provide rail-to-rail input and output.

The devices have excellent AC performance with 78-kHz

bandwidth, 20-V/ms slew rate while only drawing 9.8-μA

quiescent current per amplifier.

Rail-to-Rail Input and Output

Gain Bandwidth Product: 78 kHz

Slew Rate: 20 V/ms

The TPA5521 and TPA5521U (1-ch veision) are offered

in the SOT23-5, DFN-4, and SC70-5 packages. The

TPA5522 (2-ch version) is available in the SOP-8,

TSSOP-8, MSOP-8, and DFN-8 packages. All versions

can be operated over the industrial temperature range of

−40°C to +125°C.
