Product details
Overview
TLV9044IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output (RRIO), ultra-low-voltage operational amplifier optimized for power-constrained systems. It operates from 1.2 V to 5.5 V supply, draws only 10 µA per channel, features ±0.6 mV input offset voltage and 350 kHz gain-bandwidth product, and supports –40°C to +125°C operation - enabling use in coin-cell-powered wearable sensors and low-power IoT front-ends.
For engineers reviewing the TLV9044IPWR datasheet, TLV9044IPWR pinout, TLV9044IPWR application, or TLV9044IPWR equivalent, this page delivers verified specifications, SOIC-14 package mapping, real-world use cases in current sensing and motion detection, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9044IPWR implements a low-power CMOS input stage with 1 pA typical input bias current and integrated RFI/EMI filtering on all input pins. Its unity-gain stable architecture supports direct connection to capacitive loads up to 100 pF without external compensation.
It delivers rail-to-rail output swing within 1–8 mV of either rail under 10–100 kΩ loads and maintains 60–77 dB common-mode rejection across its full temperature range and supply voltage span (1.2 V to 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 5.5 V - enables direct operation from single 1.5 V coin cells or 3.3 V/5 V rails |
| Quiescent Current | 10 µA per channel - reduces battery drain in always-on sensor nodes |
| Input Offset Voltage | ±0.6 mV (typ) - ensures <1% error in 100 mV full-scale unidirectional current sensing |
| Gain-Bandwidth Product | 350 kHz - supports DC–100 Hz biosignal amplification with margin |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-impedance pH or photodiode interfaces |
| Rail-to-Rail I/O | Full swing from V– to V+ - maximizes dynamic range in single-supply 1.2 V systems |
| Operating Temperature | –40°C to +125°C - qualified for industrial and automotive cabin ambient environments |
Pinout & Package
TLV9044IPWR is supplied in a 14-pin SOIC (D) package measuring 8.65 mm × 6.0 mm, with standard lead pitch and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - each drives ≥10 kΩ load with rail-to-rail swing |
| 2, 6, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs - high-impedance CMOS nodes (100 GΩ || 0.5 pF) |
| 3, 5, 10, 12 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs - support common-mode range from V– to V+ |
| 4 | V+ | Positive supply - accepts 1.2–5.5 V; decoupling capacitor required |
| 11 | V– | Negative supply or ground - reference for single-supply operation |
| No pin | NC | No internal connection - no routing or termination needed |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage | Operates down to 1.2 V - one of few op-amps supporting alkaline/coin-cell battery discharge curves |
| Micro-power consumption | 10 µA/ch quiescent current - extends 10 mA·h coin cell life to >1 year in continuous sensing |
| Integrated EMI filtering | On-chip RFI/EMI rejection filters - reduce susceptibility to GSM/Bluetooth interference in wearables |
| No phase reversal | Robust input overdrive behavior - prevents latch-up during transient input excursions beyond rails |
| Unity-gain stability | Stable at G = 1 with 100 pF capacitive load - eliminates need for isolation resistors in sensor buffering |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004IPWR | Higher quiescent current (60 µA/ch), lower GBW (1 MHz), no EMI filtering | Better speed for higher-frequency sensor signals; less suitable for EMI-prone wearable RF environments | Choose when bandwidth >350 kHz is required and EMI immunity is secondary |
| LPV821DR | Lower quiescent current (650 nA/ch), lower GBW (6.5 kHz), no RRIO output | Superior battery life for intermittent wake-up sensing; insufficient for rail-swing analog front-ends | Choose for ultra-low-power event-triggered systems where output swing beyond 0.2 V of rails is acceptable |
Compared with TLV9044IPWR, TLV9004IPWR trades EMI robustness and micro-power for bandwidth, while LPV821DR sacrifices output swing and speed to achieve nanoamp quiescent current - making TLV9044IPWR the optimal balance for continuous, rail-swing, low-voltage sensor interfacing.

FAQ
What is the minimum supply voltage for TLV9044IPWR?
The TLV9044IPWR operates down to 1.2 V, enabling direct use with 1.5 V alkaline or lithium coin cells across their full discharge curve. This specification is guaranteed over the full –40°C to +125°C temperature range and is not a typical-only value. The device remains fully functional, including rail-to-rail input/output and specified gain-bandwidth, at this minimum voltage.
Does TLV9044IPWR include EMI filtering?
Yes, TLV9044IPWR integrates on-chip RFI and EMI rejection filters on all input pins, as confirmed in the official datasheet Features section and Functional Description. This design reduces sensitivity to 900 MHz and 2.4 GHz interference from nearby wireless transceivers - a critical feature for wearable and portable electronics where board-level shielding is impractical.
What is the input offset voltage specification for TLV9044IPWR?
The TLV9044IPWR has a maximum input offset voltage of ±2.25 mV at 25°C and ±2.5 mV over the full –40°C to +125°C temperature range. The typical value is ±0.6 mV. This parameter is measured under standard conditions (VS = 1.2–5.5 V, RL = 100 kΩ to VS/2) and directly impacts accuracy in precision DC-coupled applications such as current sensing and bridge amplification.
Is TLV9044IPWR unity-gain stable?
Yes, TLV9044IPWR is unity-gain stable and characterized to drive ≥100 pF capacitive loads without external compensation. This is explicitly stated in the datasheet Features list and verified in Typical Characteristics (Figure 6-31, Phase Margin vs Capacitive Load). Stability is maintained across the full supply (1.2–5.5 V) and temperature (–40°C to +125°C) ranges.
What package type is used for TLV9044IPWR?
TLV9044IPWR uses the SOIC-14 (D) package, measuring 8.65 mm × 6.0 mm with standard 1.27 mm lead pitch. This is confirmed in the Device Information table and Pin Configuration section of the datasheet. The 'PWR' suffix denotes tape-and-reel packaging for automated assembly, not a different physical package variant.
