Product details
Overview
TLV9004IRTER from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-power, cost-sensitive systems operating from 1.8 V to 5.5 V supply. It delivers ±0.4 mV input offset voltage, 1 MHz unity-gain bandwidth, 60 µA per channel quiescent current, and 27 nV/√Hz broadband noise-enabling precision signal conditioning in space-constrained smoke detectors and wearable electronics.
For engineers reviewing the TLV9004IRTER datasheet, TLV9004IRTER pinout, TLV9004IRTER application, or TLV9004IRTER equivalent, key selection criteria include capacitive-load drive capability (500 pF), resistive open-loop output impedance for stable high-capacitance interfacing, extended temperature range (–40°C to 125°C), and integrated RFI/EMI filtering for noisy environments.
Technical Context
The TLV9004IRTER implements a scalable CMOS architecture with unity-gain stability and no phase reversal under overdrive. Its resistive open-loop output impedance simplifies compensation when driving loads up to 500 pF-critical for sensor interfaces with long traces or ADC input capacitance.
It operates across 1.8 V to 5.5 V single-supply or split-supply configurations, supports rail-to-rail input common-mode range (including V–), and features internal EMI rejection filters to suppress RF interference without external components-reducing BOM count in consumer and industrial end equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V/5 V logic rails without level-shifting |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing, active filtering, and sensor amplification up to ~100 kHz closed-loop |
| Input Offset Voltage | ±0.4 mV - ensures <1% error in 100 mV full-scale current-sense applications without trimming |
| Quiescent Current / Ch | 60 µA - allows four independent amplifiers to operate continuously on <250 µA total, ideal for battery-powered wearables |
| Input Bias Current | 5 pA - minimizes voltage error across high-impedance sources (e.g., thermistors, pH electrodes) |
| Capacitive Load Drive | 500 pF - supports direct connection to SAR ADC inputs and long PCB traces without oscillation |
| EMI Rejection | Integrated filter - suppresses GSM/ISM-band interference without external RC snubbers or ferrites |
Pinout & Package
TLV9004IRTER is packaged in a 16-pin WQFN (RTE) with 3.0 mm × 3.0 mm body and exposed thermal pad. The package is RoHS-compliant, moisture-sensitive level 2a, and designed for reflow soldering with thermal pad connected to V– for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 5, 14 | OUT1, OUT2, OUT3, OUT4 | Amplifier outputs - rail-to-rail swing supports full dynamic range into ADCs or comparators |
| 2, 4, 3, 10, 12, 13, 9, 8 | IN1+, IN1−, IN2+, IN2−, IN3+, IN3−, IN4+, IN4− | Differential inputs - high-impedance, rail-to-rail common-mode range accepts signals from 0 V to V+ |
| 6, 7 | SHDN12, SHDN34 | Independent dual shutdown controls - reduces total supply current to <1 µA when channels are idle |
| 2, 11 | V+, V− | Power rails - V− may be grounded in single-supply operation; thermal pad must connect to V− |
| 6, 7 | NC | No internal connection - pins 6 and 7 are unused and must remain unconnected or grounded |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of supply rails in single-supply systems-no headroom loss at input or output |
| Resistive open-loop output impedance | Eliminates need for isolation resistors when driving >100 pF loads, reducing component count and board area |
| Integrated RFI/EMI filter | Rejects 400 MHz–2.5 GHz interference without external filtering-critical for EPOS and barcode scanners |
| Extended temperature range | –40°C to 125°C operation supports deployment in HVAC control modules and motor-drive feedback circuits |
| Shutdown mode | Two independent control lines (SHDN12/SHDN34) allow selective power-down of channel pairs to optimize system-level power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004IPWR | Same electrical specs; TSSOP-14 package (4.4 mm × 5.0 mm), no shutdown pins, no thermal pad | Suitable for legacy PCBs with TSSOP footprints; lacks independent shutdown and thermal performance of WQFN | Select when footprint compatibility with existing TSSOP layouts is required and thermal load is low |
| LMV324IDR | Higher quiescent current (130 µA/ch), lower bandwidth (1.4 MHz), no EMI filter, wider offset (±3 mV) | Broadly compatible but less suited for battery-powered or EMI-heavy environments like barcode scanners | Choose only if cost is primary constraint and system tolerates higher power and reduced noise immunity |
Compared with TLV9004IPWR, TLV9004IRTER offers superior thermal management and channel-level power control; compared with LMV324IDR, it delivers 2.2× lower quiescent current, 7.5× lower input offset, and built-in EMI suppression-making it the preferred choice for next-generation portable and industrial sensing nodes.

FAQ
What is the maximum capacitive load the TLV9004IRTER can drive stably?
The TLV9004IRTER is characterized to drive up to 500 pF capacitive load stably without external compensation. This capability stems from its resistive open-loop output impedance, which avoids peaking and oscillation commonly seen with standard op amps driving ADC inputs or long PCB traces. For loads exceeding 500 pF, a small series resistor (10–50 Ω) at the output is recommended. This specification applies directly to the TLV9004IRTER in its 16-pin WQFN package under recommended operating conditions.
Does the TLV9004IRTER support true single-supply operation down to 1.8 V?
Yes, the TLV9004IRTER supports true single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input stage accepts common-mode voltages from V− (ground) to V+, and its rail-to-rail output swings within 10 mV of each rail under light load. This enables direct interfacing with 1.8 V microcontrollers and low-voltage ADCs without level-shifting circuitry. All key specifications-including offset voltage, bandwidth, and noise-are guaranteed across this full supply range for the TLV9004IRTER.
How does the shutdown functionality work on the TLV9004IRTER?
The TLV9004IRTER features two independent shutdown pins: SHDN12 controls channels 1 and 2, while SHDN34 controls channels 3 and 4. Driving either pin low disables its associated pair, reducing quiescent current to <1 µA per disabled pair. Both pins default to active-high operation with internal pull-up resistors. This dual-control architecture allows flexible power sequencing-for example, keeping sensor-conditioning channels active while powering down display drivers. The behavior is fully specified and tested for the TLV9004IRTER in its WQFN package.
Is the TLV9004IRTER pin-compatible with other TLV900x variants?
No, the TLV9004IRTER (16-pin WQFN) is not pin-compatible with other TLV9004 packages such as SOIC-14, TSSOP-14, or X2QFN-14. Pin counts, pinouts, and terminal assignments differ significantly across packages-even among TLV9004 variants. For example, the SOIC-14 version has no shutdown pins and assigns V− to pin 11, whereas TLV9004IRTER places V− on pin 11 *and* uses pins 6 and 7 for SHDN12/SHDN34. Always verify the specific pin configuration table for TLV9004IRTER before PCB layout.
What thermal considerations apply to the TLV9004IRTER's exposed pad?
The TLV9004IRTER's exposed thermal pad (pin A1) must be soldered to a PCB copper pour connected to V− (ground in single-supply systems) to ensure proper thermal dissipation and electrical stability. TI specifies junction-to-board thermal resistance (ψJB) of 25.2°C/W for this configuration. Failure to connect the pad results in >30°C higher junction temperature under full load, potentially degrading offset drift and long-term reliability. This requirement is mandatory for all designs using the TLV9004IRTER WQFN package.
