Product details
Overview
TLV9004IDR 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 robust 500 pF capacitive-load drive-enabling precision sensor signal conditioning in smoke detectors and wearable electronics.
For engineers reviewing the TLV9004IDR datasheet, TLV9004IDR pinout, TLV9004IDR application, or TLV9004IDR equivalent, key selection criteria include its rail-to-rail I/O swing at 1.8-V operation, resistive open-loop output impedance for stable high-capacitance driving, integrated RFI/EMI filtering, and extended –40°C to 125°C temperature range suitability for HVAC and motor control front-ends.
Technical Context
The TLV9004IDR implements a scalable CMOS op-amp architecture with unity-gain stability and no phase reversal under overdrive. Its resistive open-loop output impedance simplifies compensation when driving >500 pF loads-unlike conventional op-amps requiring external isolation resistors.
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/RFI rejection filters-critical for noisy industrial and appliance environments where analog front-ends interface with microcontrollers or ADCs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004IPWR | TSSOP-14 package (4.40 mm × 5.00 mm); identical electrical specs; 10% smaller footprint than SOIC-14 | Better suited for space-constrained PCBs where height clearance <1.2 mm is required | Select TLV9004IPWR when board area is constrained but thermal dissipation remains adequate (θJA = 129.7°C/W) |
| LM324DR | Higher 1.2 mA/ch quiescent current; wider 3–36 V supply range; no rail-to-rail input; 1.2 MHz GBW | Legacy industrial designs requiring higher supply voltage or legacy footprint compatibility | Choose LM324DR only if existing layout cannot accommodate 1.8-V operation or rail-to-rail I/O requirements |
Compared with TLV9004IPWR, TLV9004IDR offers superior thermal performance (207.9 vs. 129.7°C/W) in high-ambient environments, while LM324DR trades 20× higher power for broader voltage flexibility-making TLV9004IDR optimal for new ultra-low-power, compact designs.

FAQ
What is the maximum capacitive load the TLV9004IDR can drive stably?
The TLV9004IDR is characterized to drive up to 500 pF capacitively without external compensation. Its resistive open-loop output impedance enables stable operation even with much higher loads-verified up to 1 nF in typical configurations. This eliminates series output resistors in LCD bias and DAC buffer applications, reducing component count and board space in TLV9004IDR-based designs.
Does the TLV9004IDR support single-supply operation at 1.8 V?
Yes, the TLV9004IDR is fully specified for single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input includes the negative rail (V–, typically ground), and rail-to-rail output swings within 10 mV of both rails at 1.8 V. This makes TLV9004IDR ideal for direct interfacing with 1.8-V microcontrollers and low-voltage sensors without level-shifting circuitry.
Is the TLV9004IDR pin-compatible with other quad op-amps like the LM324?
No, the TLV9004IDR is not pin-compatible with the LM324 or other legacy quad op-amps. Its SOIC-14 pinout follows TI's TLV900x family layout (e.g., IN1– on pin 2, V+ on pin 4), differing from LM324's DIP/SOIC-14 assignment. Migration requires PCB layout revision. Always verify pin functions using Table 6-5 in the TLV9004IDR datasheet before redesign.
What is the input bias current specification for TLV9004IDR?
The TLV9004IDR has a maximum input bias current of 5 pA at 25°C, typical of CMOS-input op-amps. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance stages) and ensures stable DC accuracy in precision integrators. The spec is guaranteed over the full –40°C to 125°C temperature range per TLV9004IDR characterization data.
Does TLV9004IDR include EMI/RFI filtering, and how effective is it?
Yes, the TLV9004IDR integrates an internal RFI and EMI rejection filter. Test data shows >40 dB attenuation of 900-MHz GSM burst noise at the input pins, significantly improving immunity in electrically noisy environments such as smart home hubs, HVAC controllers near Wi-Fi routers, and industrial PLCs. This built-in filtering reduces or eliminates the need for external ferrite beads or RC filters in TLV9004IDR signal chains.
