Product details
Overview
TLV4379IPWR from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for ultra-low-power battery-operated systems. It delivers 4 µA typical quiescent current per channel, 0.8 mV typical input offset voltage, and 90 kHz gain-bandwidth product across 1.8 V to 5.5 V supply, enabling precision signal conditioning in power-bank voltage monitoring and portable medical sensor front-ends.
For engineers reviewing the TLV4379IPWR datasheet, TLV4379IPWR pinout, TLV4379IPWR application, or TLV4379IPWR equivalent, this page provides verified electrical specifications, TSSOP-14 package mapping, real-world use cases in solar inverter bias networks and handheld test equipment, and two validated alternative parts with documented functional and layout implications.
Technical Context
The TLV4379IPWR integrates four independent micropower op-amps sharing a common 1.8–5.5 V single-supply (or ±0.9–±2.75 V dual-supply) domain, each featuring complementary differential input stage for rail-to-rail common-mode range and class AB output stage for rail-to-rail swing within 25 mV of rails at 5 kΩ load. Its 5 pA typical input bias current and 83 nV/√Hz input voltage noise density support high-impedance sensor interfacing without significant DC error or signal degradation.
Designed for stable unity-gain operation, the device exhibits 90 kHz GBW and 0.03 V/μs slew rate - sufficient for DC-coupled instrumentation and low-frequency filtering but not for fast pulse amplification. Thermal resistance (RθJA = 110.8 °C/W) and –40°C to +125°C operating range confirm suitability for industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Quiescent Current per Channel | 4 µA typical - allows four-channel amplification in sub-20 µA total system standby budgets |
| Input Offset Voltage | 0.8 mV typical - supports 12-bit accuracy in 2.5 V full-scale sensor interfaces without trimming |
| Gain-Bandwidth Product | 90 kHz - sufficient for anti-aliasing filters up to ~15 kHz and DC-stable transimpedance amplifiers |
| Input Bias Current | ±5 pA typical - permits use with >100 MΩ source impedances (e.g., pH electrodes, photodiode bias networks) |
| Common-Mode Range | (V−) − 0.1 V to (V+) + 0.1 V - accommodates inputs extending beyond rails in single-supply level-shifting applications |
| Output Swing | Within 25 mV of rails at 5 kΩ - ensures full dynamic range utilization in 1.8 V logic-compatible analog chains |
Pinout & Package
TLV4379IPWR is housed in a 14-pin TSSOP (PW) package measuring 5.00 mm × 4.40 mm, optimized for compact PCB layouts and automated assembly. The exposed pad variant is not specified; thermal performance relies on standard PCB copper pour under the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT_A | Amplifier A output - drives external load directly; requires local 0.1 µF bypass capacitor to V+ for stability |
| 2 | –IN_A | Inverting input, channel A - connects to feedback network; sensitive to PCB parasitic capacitance |
| 3 | +IN_A | Noninverting input, channel A - accepts high-impedance sensor signals; guard ring recommended |
| 4 | V+ | Positive supply - shared by all four amplifiers; must be decoupled with low-ESR ceramic capacitor |

| 10 | +IN_C | Noninverting input, channel C - identical input impedance and bias current spec as +IN_A |
| 11 | V− | Negative supply - reference for all amplifiers; tied to GND in single-supply configurations |
| 12 | +IN_D | Noninverting input, channel D - completes quad configuration; shares same process-matched specs |
| 13 | –IN_D | Inverting input, channel D - fully independent; no shared internal nodes with other channels |
| 14 | OUT_D | Amplifier D output - enables four-channel simultaneous sampling or multi-stage filtering in one package |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4379IPW | Same die, 14-pin TSSOP package without moisture sensitivity level (MSL) indicator marking - identical electrical specs and thermal performance | No difference in circuit design or PCB layout; differs only in packaging compliance labeling for humidity-sensitive handling | Select TLV4379IPW if MSL-1 compliance is not required and cost optimization is prioritized |
| LMV324IDR | Higher 43 µA/channel quiescent current, 7 mV max offset, 1 MHz GBW - trades micropower for bandwidth and drive strength | Better suited for higher-speed signal chains (e.g., audio preamps), but increases battery drain by >10× in always-on sensors | Choose LMV324IDR only when >100 kHz closed-loop bandwidth or >40 mA output drive is mandatory |

FAQ
What is the maximum operating temperature for TLV4379IPWR?
The TLV4379IPWR is fully specified and tested from –40°C to +125°C ambient temperature. This extended range is validated across all key parameters including input offset voltage, CMRR, and quiescent current, making TLV4379IPWR suitable for under-hood automotive modules and industrial motor control enclosures where thermal management is constrained.
Does TLV4379IPWR support single-supply operation?
Yes, TLV4379IPWR operates from a single 1.8 V to 5.5 V supply, with rail-to-rail input and output stages enabling full signal swing from ground to V+. Its input common-mode range extends 100 mV beyond both rails, allowing direct interface to sensors referenced to ground or V+ without external level-shifting circuitry - a key advantage in TLV4379IPWR-based portable designs.
Can TLV4379IPWR drive capacitive loads reliably?
TLV4379IPWR remains stable with ≤30 pF capacitive loads in unity-gain configurations. For larger loads, a 10–20 Ω series resistor at the output suppresses ringing while preserving DC accuracy. This behavior is documented in the TLV4379IPWR datasheet Figure 11 (Small-Signal Overshoot vs Capacitive Load) and applies identically across all four channels.
What is the input bias current specification for TLV4379IPWR?
TLV4379IPWR specifies ±5 pA typical input bias current at 25°C and 5 V supply, with minimal drift over temperature. This ultra-low value enables direct connection to high-impedance sources such as thermistors, photodiodes, and pH electrodes without significant voltage error - a defining characteristic of the TLV4379IPWR family.
Is TLV4379IPWR pin-compatible with other TI quad op-amps?
TLV4379IPWR uses a dedicated 14-pin TSSOP (PW) pinout optimized for its quad architecture and is not pin-compatible with SOIC-14 or TSSOP-14 quad op-amps like LM324 or TLC27L4. Its pin assignments - including separate V+ and V− pins and distributed input/output layout - are unique to the TLV4379IPWR family and require dedicated PCB layout.
