Texas Instruments TLV9151SIDBVR

Overview

TLV9151SIDBVR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for precision industrial signal conditioning. It delivers ±125 µV offset voltage, 4.5-MHz gain-bandwidth product, and 10.5 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in low-level sensor interfaces and current-sensing circuits.

For engineers reviewing the TLV9151SIDBVR datasheet, TLV9151SIDBVR pinout, TLV9151SIDBVR application, or TLV9151SIDBVR equivalent, this page provides verified electrical specifications, SOT-23-5 package details, real-world use cases in factory automation and test equipment, and validated alternative op amps with documented functional trade-offs.

Technical Context

The TLV9151SIDBVR implements a precision CMOS input stage with EMI/RFI filtering on both inputs, supporting differential and common-mode input voltages extending to the supply rails. Its 20 V/µs slew rate and 75 mA output drive capability enable fast settling into capacitive loads up to 1000 pF without instability.

It operates from 2.7 V to 16 V (±1.35 V to ±8 V), features robust PSRR (±1.6 µV/V at VS = 4–16 V) and CMRR (99–130 dB), and maintains low quiescent current (560 µA per amplifier) across –40°C to +125°C - making it suitable for wide-temperature industrial analog front-ends.

FAQ

What is the maximum capacitive load the TLV9151SIDBVR can drive stably?

The TLV9151SIDBVR is specified to drive up to 1000 pF capacitive load while maintaining stability and ≥60° phase margin in unity-gain configuration. This capability eliminates the need for external isolation resistors in many sensor interface and DAC output buffer applications, reducing board space and component count. The device's internal compensation and 20 V/µs slew rate ensure clean step response even under heavy capacitive loading - confirmed in Figure 6-27 through Figure 6-29 of the TLV9151SIDBVR datasheet.

Does the TLV9151SIDBVR have a shutdown function?

No, the TLV9151SIDBVR (SOT-23-5 DBV package) does not include a shutdown pin. Shutdown functionality is only available in the TLV9151S variants (e.g., TLV9151SIDBVT with 6-pin SOT-23), which add a dedicated SHDN pin that disables the amplifier when driven high. The TLV9151SIDBVR remains active whenever powered within its 2.7 V to 16 V supply range and draws 560 µA quiescent current continuously. For power-sensitive designs requiring disable capability, TLV9151SIDBVT is the direct functional counterpart.

What is the common-mode input voltage range of the TLV9151SIDBVR?

The TLV9151SIDBVR supports a common-mode input voltage range from (V–) – 0.1 V to (V+) + 0.1 V, fully rail-to-rail inclusive. This allows the device to accurately amplify signals near or beyond the supply rails - such as sensor outputs referenced to ground in single-supply systems or differential signals riding on high common-mode voltages in industrial buses. The specification is guaranteed across the full –40°C to +125°C operating temperature range and applies to both input terminals simultaneously, enabling robust performance in noisy, high-voltage environments.

Can the TLV9151SIDBVR operate from a single 3.3-V supply?

Yes, the TLV9151SIDBVR is fully specified for operation from a single 3.3-V supply (V+ = 3.3 V, V– = 0 V). Its rail-to-rail input and output stages deliver usable output swing within 12 mV of each rail under 10-kΩ load, and its 560 µA quiescent current minimizes power impact. All key parameters - including ±125 µV offset, 4.5-MHz GBW, and 10.5 nV/√Hz noise - are characterized at 3.3 V and remain valid across –40°C to +125°C, making it ideal for modern low-voltage industrial IoT nodes and portable instrumentation.

How does the TLV9151SIDBVR handle electromagnetic interference (EMI)?

The TLV9151SIDBVR integrates EMI/RFI filters on both input pins, achieving >30 dB rejection across 100 MHz to 1 GHz per Figure 6-41 of its datasheet. This built-in filtering eliminates the need for external RC networks in applications exposed to RF fields - such as factory automation near variable-frequency drives or wireless microphone receivers co-located with Bluetooth/Wi-Fi modules. The filter design preserves DC precision and AC bandwidth, ensuring EMI suppression does not degrade 4.5-MHz GBW or 10.5 nV/√Hz noise performance.
