Product details
Overview
TLV9164IDR from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for precision signal conditioning in industrial and test equipment. It delivers ±210 µV offset voltage, 11 MHz gain-bandwidth product, 33 V/µs slew rate, 6.8 nV/√Hz input voltage noise at 1 kHz, and operates from 2.7 V to 16 V supply. It is used in high-side/low-side current sensing and multiplexed data acquisition systems.
For engineers reviewing the TLV9164IDR datasheet, TLV9164IDR pinout, TLV9164IDR application, or TLV9164IDR equivalent, this page provides verified electrical specifications, package-validated pin functions, real-world use cases in factory automation and professional audio, and two confirmed alternative op amps with documented functional trade-offs.
Technical Context
The TLV9164IDR employs a CMOS input stage enabling ±10 pA bias current and rail-to-rail common-mode input range extending to both supply rails. Its architecture supports open-loop comparator operation and MUX-friendly differential inputs without phase reversal.
It features unity-gain stability, 110 dB common-mode rejection (CMRR) at DC, and robust electromagnetic interference rejection (EMIRR) up to 120 dB at 1 GHz - critical for noisy industrial environments where signal integrity must be preserved across all four channels simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 11 MHz - enables stable closed-loop operation up to 10× gain with predictable phase margin. |
| Input offset voltage | ±0.21 mV (typ) - ensures ≤210 µV initial error in precision sensor front-ends without trimming. |
| Slew rate | 33 V/µs - supports fast settling of 10 V step signals within 0.7 µs to 0.1% accuracy. |
| Input voltage noise density | 6.8 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and low-level analog signal chains. |
| Supply voltage range | 2.7 V to 16 V - compatible with single-supply 3.3 V, 5 V, and dual-supply ±8 V systems. |
| Quiescent current per channel | 2.4 mA - balances performance and power in multi-channel instrumentation with thermal constraints. |
| Common-mode rejection ratio | 110 dB (DC) - rejects >99.999% of shared-mode interference in high-impedance sensor interfaces. |
Pinout & Package
TLV9164IDR is housed in a 14-pin SOIC (D) package measuring 8.65 mm × 6.00 mm, rated for operation from –40°C to +125°C. Thermal resistance RθJA is 99.0°C/W, supporting reliable performance in compact industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier output terminals - each drives ≥±73 mA short-circuit current and swings within 6 mV of rails under no load. |
| 2, 6, 9, 13 | IN1––IN4– | Inverting inputs - accept rail-to-rail common-mode voltages and support comparator mode when open-loop. |
| 3, 5, 10, 12 | IN1+–IN4+ | Noninverting inputs - matched to inverting inputs for <0.4 µV/V channel separation and low THD+N (0.00005%). |
| 4 | V+ | Positive supply terminal - connects to highest potential rail (up to +16 V or +8 V in dual supply). |
| 11 | V– | Negative supply terminal - connects to lowest potential rail (down to –8 V or ground in single supply). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage 2.7 V systems and high-precision 16 V applications without headroom loss. |
| MUX-friendly/comparator inputs | Allows direct connection to analog multiplexers and operation as a comparator without external clamping diodes. |
| Low offset drift | ±0.25 µV/°C - maintains calibration stability over –40°C to +125°C ambient without active compensation. |
| High EMIRR performance | ≥100 dB rejection up to 1 GHz - mitigates RF-induced errors in factory automation and wireless test equipment. |
| Unity-gain stable | Eliminates need for external compensation in buffer, gain-of-one, or transimpedance configurations. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), lower noise (5.7 nV/√Hz), but dual-channel only and higher quiescent current (700 µA per amp). | Best for ultra-low-offset DC-critical designs where channel count is secondary and power budget allows. | Select OPA2182IDR when sub-10 µV offset dominates over quad integration and supply current. |
| LM324BDR | Wider temperature range (–40°C to +125°C), but higher offset (±1.5 mV), lower GBW (1.2 MHz), and no rail-to-rail input. | Suitable for cost-sensitive, non-precision industrial controls where bandwidth and DC accuracy are relaxed. | Choose LM324BDR only if design tolerates >7× higher offset and 9× lower bandwidth than TLV9164IDR. |
Compared with OPA2182IDR and LM324BDR, TLV9164IDR uniquely delivers quad-channel integration, 11 MHz bandwidth, rail-to-rail input, and <210 µV offset in a single SOIC-14 package - making it optimal for space-constrained, multi-sensor industrial systems requiring balanced AC/DC performance.

FAQ
What is the operating temperature range for TLV9164IDR?
The TLV9164IDR is specified from –40°C to +125°C ambient temperature, validated across its full electrical performance envelope including offset voltage, CMRR, and slew rate. This range meets industrial-grade requirements for deployment in motor drives, PLCs, and outdoor test equipment where thermal extremes are encountered.
Does TLV9164IDR support rail-to-rail input and output simultaneously?
Yes, TLV9164IDR supports rail-to-rail input common-mode voltage (from V– to V+) and rail-to-rail output swing (within 6 mV of rails at no load). This capability enables full utilization of supply voltage headroom in single-supply 3.3 V or 5 V systems, critical for maximizing ADC dynamic range in data-acquisition front-ends.
What is the maximum capacitive load TLV9164IDR can drive stably?
TLV9164IDR maintains ≥64° phase margin with up to 200 pF capacitive load in unity-gain configuration, as confirmed by Figure 5-33 in the datasheet. For loads exceeding 200 pF, external isolation resistor (RISO) is recommended to prevent peaking or oscillation - especially in PCB traces driving remote sensors or cables.
How does TLV9164IDR perform in high-EMI environments like factory floors?
TLV9164IDR achieves ≥100 dB electromagnetic interference rejection ratio (EMIRR) up to 1 GHz, as shown in Figure 5-40. This allows it to maintain signal integrity in proximity to variable-frequency drives, RF welders, and wireless infrastructure - a key differentiator versus standard precision op amps lacking dedicated EMI-hardened input stages.
Is TLV9164IDR pin-compatible with other quad op amps in SOIC-14 packages?
No, TLV9164IDR has a unique pinout optimized for quad-channel symmetry: IN+/IN– pairs are interleaved across all four channels, with dedicated V+ and V– pins. It is not pin-compatible with legacy SOIC-14 quad op amps like LM324 or TL074 - PCB layout must follow TI's Figure 4-7 pin map to ensure correct channel routing and supply decoupling.
