Product details
Overview
TLV9104IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in industrial and communications systems. It delivers 1.1-MHz gain-bandwidth, ±300 µV max input offset voltage, 120 µA per amplifier quiescent current, and operates from 2.7 V to 16 V single supply (±1.35 V to ±8 V dual). It is used in baseband unit (BBU) analog front-ends for sensor signal amplification and filtering.
For engineers reviewing the TLV9104IPWR datasheet, TLV9104IPWR pinout, TLV9104IPWR application, or TLV9104IPWR equivalent, this page provides verified electrical specifications, SOIC-14 package mapping, shutdown timing (11 µs enable / 2.5 µs disable), rail-to-rail output swing (≤60 mV from rail at 10 kΩ), and real-world application context for optical modules and portable test equipment.
Technical Context
The TLV9104IPWR integrates four independent high-precision op-amp channels with matched AC/DC performance across –40°C to +125°C. Its input stage supports rail-to-rail common-mode range (V– –0.2 V to V+ +0.2 V) and achieves 110 dB CMRR at 16 V supply, enabling accurate sensing near supply rails. The output stage drives ±80 mA and sustains 4.5 V/µs slew rate into 20 pF load, supporting fast settling (2 µs to 0.1% for 2-V step).
Each channel features dedicated shutdown control via SHDN12 and SHDN34 pins, reducing quiescent current to 20–30 µA per amplifier when disabled. Input bias current is ultra-low (±10 pA), and input voltage noise is 28 nV/√Hz at 10 kHz - critical for high-impedance sensor interfaces in macro remote radio units (RRUs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 1.1 MHz - enables stable unity-gain buffer or G = 10 amplification up to ~110 kHz without phase margin loss. |
| Input offset voltage (max) | ±1.5 mV at 25°C - ensures ≤1.5 mV DC error in precision instrumentation amplifier front-ends. |
| Quiescent current per channel | 115–150 µA - allows four-channel operation at <600 µA total, suitable for battery-powered portable test gear. |
| Output voltage swing | Within 60 mV of rails at 10 kΩ - preserves dynamic range in 3.3-V or 5-V single-supply data acquisition systems. |
| Slew rate | 4.5 V/µs - supports clean 10-Vpp, 100-kHz sine wave output without distortion in active filters. |
| Shutdown current (per amp) | 20–30 µA - reduces system standby power by >95% versus active mode, critical for always-on RRU monitoring circuits. |
| Common-mode rejection | 110 dB at 16 V - rejects >99.999% of coupled supply noise in noisy industrial PLC analog inputs. |
Pinout & Package
TLV9104IPWR is packaged in a 14-pin SOIC (D) body measuring 8.65 mm × 3.90 mm, with exposed pad option not present in this variant. Pin functions are fully defined per TI SBOS943E Rev E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1, OUT2, OUT3, OUT4 | Amplifier outputs - each capable of ±80 mA drive and rail-to-rail swing; require local 100-nF bypass to V–. |
| 2, 6, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs - high-impedance (6 TΩ || 1 pF), sensitive to PCB leakage; guard traces recommended. |
| 3, 5, 10, 12 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs - rail-to-rail common-mode range supports direct connection to resistive sensor bridges. |
| 4 | V+ | Positive supply - accepts 2.7–16 V; must be decoupled with ≥1 µF ceramic capacitor close to pin. |
| 11 | V– | Negative supply - referenced to system ground in single-supply configs; connects to thermal pad in WQFN variants (not applicable here). |
| - | NC (pins 6, 7 on some variants) | No-connect - unused pins on SOIC-14; leave unconnected and unpopulated on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal capture from 0 V to V+ in single-supply systems without level-shifting circuitry. |
| Low offset drift (±0.6 µV/°C) | Maintains <10 µV total offset shift over –40°C to +125°C - eliminates need for periodic calibration in outdoor telecom hardware. |
| Robust EMIRR (77 dB @ 1.8 GHz) | Rejects cellular band interference in macro RRU enclosures, preventing demodulation artifacts in analog IF paths. |
| Shutdown control (SHDN12/SHDN34) | Independent two-channel shutdown pairs allow selective power gating - e.g., disable ADC driver amps during sleep while keeping bias generators active. |
| High output current (±80 mA) | Drives 2-kΩ loads with <300 mV headroom at 16 V - sufficient for driving SAR ADC reference buffers or LED bias circuits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333PWR | Lower offset (±2 µV), higher IQ (17 µA per amp), no shutdown, 360-kHz GBW | Better DC precision but insufficient bandwidth for >100-kHz signal chains; unsuitable for RRU IF stages. | Select when ultra-low drift (<0.05 µV/°C) dominates over speed and power; verify layout for chopper noise sensitivity. |
| LM324DR | Higher offset (±3 mV), no rail-to-rail IO, 1.2-mA IQ per amp, 1.2-MHz GBW | Legacy part with poor PSRR (70 dB) and limited common-mode range - fails in 3.3-V single-supply sensor nodes. | Acceptable only for cost-sensitive, non-precision AC-coupled audio or comparator hysteresis circuits; avoid for BBU/RRU use. |
Compared with TLV9104IPWR, OPA2333PWR trades bandwidth and shutdown for nanovolt-level DC stability, while LM324DR sacrifices rail-to-rail operation and power efficiency for legacy compatibility - neither matches TLV9104IPWR's balanced precision, speed, and ultra-low power in modern industrial signal chains.

FAQ
What is the maximum supply voltage for TLV9104IPWR?
The TLV9104IPWR supports an absolute maximum supply voltage of 20 V (V+ – V–), with recommended operation from 2.7 V to 16 V. Exceeding 16 V risks parametric degradation, while operation below 2.7 V may cause reduced open-loop gain and increased input offset voltage drift. Always observe the 0.5-V input overvoltage limit relative to rails.
Does TLV9104IPWR support true rail-to-rail output swing under load?
Yes - TLV9104IPWR achieves output swing within 60 mV of each rail at 10 kΩ load and 16 V supply, and within 200–300 mV at 2 kΩ. This rail-to-rail capability holds across –40°C to +125°C, enabling full utilization of ADC input ranges in single-supply data acquisition systems without external level-shifting components.
How does the shutdown function operate on TLV9104IPWR?
TLV9104IPWR uses two dedicated shutdown pins: SHDN12 controls channels 1 and 2, SHDN34 controls channels 3 and 4. A logic low (≤ V– + 0.2 V) enables the respective pair; a logic high (≥ V– + 1.1 V) disables it. Enable/disable times are 11 µs and 2.5 µs respectively, and quiescent current drops to 20–30 µA per disabled amplifier.
Can TLV9104IPWR drive capacitive loads without oscillation?
TLV9104IPWR is stable with up to 20 pF capacitive load in unity-gain configuration, as validated by phase margin ≥60° and overshoot data in the datasheet. For loads >20 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is required to maintain stability - critical when driving ADC input capacitance or long PCB traces in BBU analog boards.
What is the input bias current specification for TLV9104IPWR?
The TLV9104IPWR features ultra-low input bias current of ±10 pA (typical) across temperature, enabled by its CMOS input stage. This allows use with high-impedance sources (e.g., pH electrodes, photodiode TIAs, or megohm-range thermistor networks) without significant voltage error - a key differentiator versus bipolar-input op-amps like LM324.
