Product details
Overview
TLV4314IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in battery-powered and industrial systems. It delivers 3 MHz gain-bandwidth, 1.5 V/µs slew rate, ±0.75 mV typical offset voltage, 1 pA typical input bias current, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy sensor interfacing and ADC driver applications in portable medical devices and remote sensing nodes.
For engineers reviewing the TLV4314IPWR datasheet, TLV4314IPWR pinout, TLV4314IPWR application, or TLV4314IPWR equivalent, key selection criteria include its EMI-hardened architecture (EMIRR > 70 dB up to 1 GHz), extended –40°C to +125°C temperature range, 14-pin TSSOP package with verified quad-channel pin mapping, and compatibility with capacitive loads up to 300 pF without external compensation.
Technical Context
The TLV4314IPWR implements a complementary differential input stage enabling true rail-to-rail input operation - with common-mode range extending 200 mV beyond both supply rails - and a class AB output stage delivering rail-to-rail swing within 5 mV of V+ or V– under 10 kΩ load. Its internal RF/EMI filter provides 80 MHz cutoff (–3 dB) and >70 dB rejection at 100 MHz, directly addressing noise coupling in mixed-signal PCB layouts.
This quad op-amp is unity-gain stable and supports single-supply operation down to 1.8 V, making it suitable for direct interface with 12-bit and 16-bit SAR ADCs requiring wide dynamic range. Its 150 µA/channel quiescent current and 16 nV/√Hz input voltage noise at 1 kHz balance power efficiency with precision DC performance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4314IPWR | Same pinout and electrical specs, but with enhanced 1/f noise performance (0.1–10 Hz: 5 µVPP vs TLV4314's 5 µVPP) and tighter offset drift (1.5 µV/°C vs 2 µV/°C). | Better suited for ultra-low-frequency sensor applications (e.g., strain gauges, thermopiles) where long-term DC stability dominates. | Select OPA4314IPWR when sub-µV drift over temperature is required; TLV4314IPWR remains optimal for cost-sensitive, general-purpose designs. |
| MCP6004-E/ST | Lower bandwidth (1 MHz), higher offset (1.5 mV typ), no integrated EMI filter, but offers lower quiescent current (1 µA/ch) and wider supply range (1.8–6.0 V). | Targeted at ultra-low-power wake-up circuits and simple comparators; lacks EMI robustness for noisy industrial settings. | Choose MCP6004-E/ST only for standby monitoring functions; TLV4314IPWR is preferred for active signal chains requiring accuracy and noise immunity. |
Compared with OPA4314IPWR and MCP6004-E/ST, TLV4314IPWR delivers the best balance of EMI immunity, rail-to-rail performance, and production-tested 125°C operation - making it the default choice for industrial and medical signal conditioning where reliability under electrical stress is non-negotiable.

FAQ
What is the maximum capacitive load the TLV4314IPWR can drive while remaining stable?
The TLV4314IPWR is unity-gain stable with capacitive loads up to 300 pF when driving a 10 kΩ resistive load. For loads exceeding 300 pF, stability can be maintained by adding a 10–20 Ω series resistor between the output and the capacitor, though this introduces minor gain error. The device's internal compensation eliminates need for external compensation in standard sensor-buffer configurations.
Does the TLV4314IPWR support true rail-to-rail input operation across its full supply range?
Yes - the TLV4314IPWR features a complementary input stage that extends the common-mode input voltage range 200 mV beyond both V– and V+, covering (V–) – 0.2 V to (V+) + 0.2 V. This enables accurate signal acquisition near supply rails, critical for single-supply systems using 1.8 V or 3.3 V rails without level-shifting circuitry.
How does the internal EMI filter in the TLV4314IPWR improve system-level robustness?
The TLV4314IPWR integrates an on-die low-pass filter with ~80 MHz –3 dB point on both inputs, rejecting RF energy before it causes rectification-induced offset shifts. Measured EMIRR exceeds 70 dB at 100 MHz, preventing erroneous readings in environments with cellular, Wi-Fi, or switching power supply noise - a key differentiator versus generic quad op-amps.
Is the TLV4314IPWR pin-compatible with other TI quad op-amps in TSSOP-14 packages?
No - the TLV4314IPWR uses a unique pinout optimized for quad-channel independence: V+ and V– are centrally located (Pins 4 and 11), and all eight inputs plus four outputs are individually routed. It is not pin-compatible with OPA4314IPWR (same pinout) or LMV324IPWR (different pin mapping), requiring dedicated PCB layout.
What is the guaranteed quiescent current per channel for TLV4314IPWR over temperature?
The TLV4314IPWR guarantees ≤250 µA per channel across the full –40°C to +125°C operating range at 5 V supply. At room temperature and 1.8 V supply, typical current drops to 150 µA/channel - enabling four simultaneous analog channels while consuming less than 1 mA total in always-on monitoring applications.
