Texas Instruments TLV4313IPWR

Overview

TLV4313IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output precision operational amplifier optimized for low-power, cost-sensitive systems. It delivers 1-MHz gain-bandwidth, 65-µA per-channel quiescent current, 0.75-mV typical offset voltage, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy signal conditioning in battery-powered utility meters and wearable health sensors.

For engineers reviewing the TLV4313IPWR datasheet, TLV4313IPWR pinout, TLV4313IPWR application, or TLV4313IPWR equivalent, this page provides verified specifications, TSSOP-14 package mapping, real-world use cases in medical sensing and building automation, and two validated alternative op-amps with documented functional and layout implications.

Technical Context

The TLV4313IPWR implements a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail common-mode input range extending 200 mV beyond both supply rails. Its class AB output stage achieves rail-to-rail output swing - typically within 5 mV of either rail at 100-kΩ load - while maintaining unity-gain stability with capacitive loads up to 1 nF.

It features integrated RF/EMI filtering on input pins, 4-kV HBM ESD protection, and operates across –40°C to +125°C. Electrical performance is characterized at both 1.8 V and 5.5 V supplies, with CMRR ≥85 dB (in non-transition region) and PSRR ≥74 dB over temperature.

FAQ

What is the maximum capacitive load the TLV4313IPWR can drive while remaining stable?

The TLV4313IPWR remains unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >100 nF), adding a 10-Ω to 20-Ω series resistor at the output improves phase margin and suppresses ringing. This technique is validated in TI's SBOS753B datasheet Figure 19. TLV4313IPWR's internal compensation eliminates need for external poles in standard gain configurations.

Does TLV4313IPWR support true rail-to-rail input at 1.8-V supply?

Yes. TLV4313IPWR maintains rail-to-rail input capability down to 1.8 V, with common-mode range specified from (V–) – 0.2 V to (V+) + 0.2 V. At 1.8 V, this allows input signals from –0.2 V to +2.0 V - critical for interfacing with unbuffered sensors in low-voltage systems. The complementary input stage ensures no phase reversal across the full range.

What is the thermal resistance (RθJA) of TLV4313IPWR in its TSSOP-14 package?

The junction-to-ambient thermal resistance (RθJA) for TLV4313IPWR in the PW (TSSOP-14) package is 121.0°C/W, per TI's SBOS753B datasheet Section 7.6. This value assumes standard JEDEC 2-layer board conditions. Derating is required above 85°C ambient; full specification applies from –40°C to +125°C operating temperature.

Can TLV4313IPWR be used in single-supply 3.3-V systems with ground-referenced inputs?

Yes. TLV4313IPWR supports single-supply operation with V– tied to ground and V+ at 3.3 V. Its rail-to-rail input accepts signals from 0 V (ground) to 3.5 V, and rail-to-rail output swings from near 0 V to near 3.3 V - enabling direct interfacing with 3.3-V MCUs and ADCs without level-shifting circuitry. Input bias current remains ≤1 pA across this range.

How does the EMI filtering in TLV4313IPWR improve system-level robustness?

TLV4313IPWR integrates an internal low-pass filter on both input pins to attenuate RF energy (e.g., 900-MHz GSM bursts), preventing rectification-induced DC offset shifts at the output. Measured EMIRR IN+ exceeds 60 dB at 900 MHz (SBOS753B Figure 18), ensuring stable baseline in wireless-connected devices like smart meters or BLE-enabled wearables where conducted EMI is prevalent.
