Product details
Overview
TLV4333IDR from Texas Instruments is a quad-channel, zero-drift CMOS operational amplifier optimized for precision low-voltage applications. It delivers 2 µV typical input offset voltage, 0.02 µV/°C drift, 17 µA quiescent current per amplifier, rail-to-rail input/output swing, and operates from 1.8 V to 5.5 V supply. It is used in high-accuracy sensor signal conditioning circuits such as thermistor-based temperature measurement and electronic scales.
For engineers reviewing the TLV4333IDR datasheet, TLV4333IDR pinout, TLV4333IDR application, or TLV4333IDR equivalent, this page provides verified specifications, SOIC-14 and TSSOP-14 package details, real-world use scenarios, and two validated alternative parts with documented technical and application differences.
Technical Context
The TLV4333IDR employs a proprietary auto-calibration architecture that corrects input offset every 8 µs using a time-continuous 125-kHz internal op amp, eliminating 1/f flicker noise while maintaining unity-gain stability. Its input stage supports rail-to-rail common-mode range extending 100 mV beyond both supply rails, and its output swings within 30 mV of each rail under load at –40°C to +125°C.
Internal EMI filtering (–3 dB at ~8 MHz) suppresses conducted interference on both differential and common-mode paths. The device features 102 dB minimum CMRR and PSRR over frequency, enabling robust operation directly from unregulated battery sources without external regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 µV typ - enables sub-10 µV system-level error in precision DC amplification |
| Offset Drift | 0.02 µV/°C - ensures <100 nV total drift across –40°C to +125°C operating range |
| Quiescent Current | 17 µA per amplifier - allows four-channel precision amplification at <70 µA total supply current |
| Supply Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting |
| 0.1 Hz to 10 Hz Noise | 1.1 µVPP - critical for low-frequency sensor interfaces like strain gauges and thermistors |
| Gain-Bandwidth Product | 350 kHz - sufficient for anti-aliasing filters and slow-sampling data acquisition front-ends |
| Common-Mode Range | (V–) – 0.1 V to (V+) + 0.1 V - eliminates input clamping issues in rail-to-rail sensing |
Pinout & Package
TLV4333IDR is available in SOIC-14 (D package, 8.65 mm × 3.91 mm) and TSSOP-14 (PW package, 5.00 mm × 4.40 mm) packages. Both are surface-mount, RoHS-compliant, and rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A, OUT B, OUT C, OUT D | Amplifier outputs - each drives ≥10 kΩ load rail-to-rail; short-circuit protected to ±5 mA |
| 2, 6, 9, 13 | –IN A, –IN B, –IN C, –IN D | Inverting inputs - high-impedance (±70 pA bias), EMI-filtered, support 0.1 V beyond rails |
| 3, 5, 10, 12 | +IN A, +IN B, +IN C, +IN D | Noninverting inputs - matched to –IN pins; enable precision differential and instrumentation topologies |
| 4 | V+ | Positive supply - accepts 1.8 V to 5.5 V; requires 0.1 µF ceramic bypass capacitor |
| 11 | V– | Negative supply - referenced to system ground in single-supply mode; supports true 0 V output swing |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift auto-calibration | Continuous 125-kHz correction cycle eliminates 1/f noise and holds offset stable over time and temperature |
| Rail-to-rail I/O | Input extends 100 mV beyond supplies; output swings to within 30 mV of rails at full temperature range |
| Integrated EMI filtering | On-chip low-pass filter (–3 dB @ 8 MHz) reduces rectified offset shifts from RF interference |
| Low-power precision | 17 µA per channel enables 4-channel operation below 70 µA - ideal for battery-powered instrumentation |
| High PSRR & CMRR | ≥102 dB PSRR/CMRR minimizes supply and common-mode coupling in noisy industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | 2 µV max VOS, 0.02 µV/°C drift, but 19 µA per amplifier and no internal EMI filter | Suitable for lab-grade instruments where EMI immunity is managed externally; less robust in industrial EMI environments | Prefer TLV4333IDR when board-level EMI filtering is impractical or space-constrained |
| MCP6V84-E/SL | 25 µV max VOS, 0.05 µV/°C drift, 50 µA per amplifier, SC70-8 package (dual only) | Better for cost-sensitive consumer applications where 10× higher offset is acceptable; not quad-channel | Choose TLV4333IDR when quad-channel integration, ultra-low drift, and sub-70 µA total supply current are mandatory |
Compared with OPA2333AIDR and MCP6V84-E/SL, TLV4333IDR uniquely combines quad-channel integration, 2 µV offset, integrated EMI filtering, and <70 µA total quiescent current - making it the only option for space- and power-constrained precision sensor nodes requiring four independent low-drift amplifiers.

FAQ
What is the maximum operating temperature range for TLV4333IDR?
The TLV4333IDR is fully specified for continuous operation from –40°C to +125°C ambient temperature. Its electrical characteristics, including offset voltage, drift, and output swing, are guaranteed across this full industrial temperature range. Junction temperature must remain ≤150°C under all conditions, and thermal metrics (e.g., RθJA = 83.8°C/W for SOIC-14) support thermal design validation.
Does TLV4333IDR support true rail-to-rail input and output operation?
Yes, TLV4333IDR supports rail-to-rail input with a common-mode range extending 0.1 V beyond both supply rails (V– – 0.1 V to V+ + 0.1 V), and rail-to-rail output that swings to within 30 mV of each rail under load across –40°C to +125°C. This eliminates input clamping and enables direct interfacing with low-voltage ADCs and microcontrollers.
How does the auto-calibration architecture of TLV4333IDR eliminate 1/f noise?
The TLV4333IDR uses a proprietary time-continuous auto-calibration technique that corrects input offset every 8 µs via a dedicated 125-kHz internal amplifier. This architecture removes flicker (1/f) noise components entirely, resulting in flat voltage noise density (55 nV/√Hz at 1 kHz) and ultra-low 0.1–10 Hz noise (1.1 µVPP), unlike chopper-stabilized amplifiers that exhibit switching artifacts.
Can TLV4333IDR be used with a single 1.8 V supply?
Yes, TLV4333IDR is fully functional and characterized down to 1.8 V single-supply operation (V+ = 1.8 V, V– = GND). All key parameters-including offset voltage, noise, CMRR, and output swing-are specified across 1.8 V to 5.5 V. At 1.8 V, it maintains 17 µA per amplifier quiescent current and rail-to-rail I/O performance, making it ideal for coin-cell and energy-harvesting systems.
What package options are available for TLV4333IDR, and are they pin-compatible?
TLV4333IDR is offered in SOIC-14 (D package) and TSSOP-14 (PW package), both with identical 14-pin pinout and function mapping. Pin compatibility between these packages is confirmed by TI's official datasheet (SBOS751, Section 6), allowing direct PCB footprint interchangeability without layout changes-only thermal and mechanical mounting considerations differ.
