TLV4387PWR

Instrumentation, Op Amps, Buffer Amps Overview

The TLV4387PWR is a quad-channel, high-precision, zero-drift operational amplifier from Texas Instruments. It features an ultra-low maximum input offset voltage of ±10 µV and a drift of ±0.01 µV/°C. The device offers a gain-bandwidth product of 5.7 MHz, a slew rate of 2.8 V/µs, and low noise density of 8.5 nV/√Hz at 1 kHz. Operating on single supplies from 1.7 V to 5.5 V or dual supplies from ±0.85 V to ±2.75 V, it draws 570 µA per amplifier. It includes EMI/RFI filtered inputs and operates over an industrial temperature range of –40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift technology ensures ultra-low offset voltage and minimal drift over time and temperature for long-term stability.
• Low-input bias current of 300 pA (maximum) with flat bias current characteristics across the operating temperature range.
• EMI and RFI filtered inputs reduce susceptibility to electromagnetic interference and signal rectification errors.
• Rail-to-rail input and output capabilities allow operation with common-mode voltages extending beyond supply rails.

Instrumentation, Op Amps, Buffer Amps Applications

• Electronic thermometer
• Weigh scale
• Temperature transmitter
• Data acquisition (DAQ)
• Pressure transmitter

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type PW (TSSOP, 14-pin) matches the design footprint. Confirm the channel count is four, as other variants in the family offer different configurations. Ensure the operating environment stays within the specified –40°C to +125°C range. Check that power supply voltages do not exceed the absolute maximum ratings of 6 V single or ±3 V dual. Validate that the application does not require shutdown functionality, which this device lacks.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TLV4387PWR when multiple precision channels are required in a compact TSSOP package. It is suitable for applications demanding high linearity and low noise without 1/f noise components. Consider this part for interfacing with 16-bit to 24-bit ADCs where offset stability is critical. It is appropriate for battery-powered systems due to its moderate quiescent current and wide supply range.

Instrumentation, Op Amps, Buffer Amps Part Context

The TLV4387PWR belongs to the TLVx387 family of precision amplifiers, which also includes the single-channel TLV387 and dual-channel TLV2387. All members share the same core zero-drift architecture and electrical performance characteristics. The '4' prefix indicates a quad configuration, while 'PWR' specifies the 14-pin TSSOP package with a reel tape-and-reel shipping format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

TLV4387PW: Identical electrical specifications and pinout; differs only in shipping packaging (tube instead of reel).

Instrumentation, Op Amps, Buffer Amps FAQ

Does the TLV4387PWR have a shutdown pin?

No, the TLV4387PWR does not feature a shutdown mode. It remains operational whenever the power supply voltage is above 1.7 V.

What is the input common-mode voltage range?

The common-mode input range extends 100 mV to 200 mV beyond the supply rails, depending on the specific supply voltage used.

Is the device unity-gain stable?

Yes, the TLV4387PWR is designed to be unity-gain stable.
