Product details
Overview
TLV9002IDR from Texas Instruments is a dual-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 1 MHz unity-gain bandwidth, ±0.4 mV input offset voltage, 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 TLV9002IDR datasheet, TLV9002IDR pinout, TLV9002IDR application, or TLV9002IDR equivalent, key selection criteria include its capacitive-load drive capability (500 pF), resistive open-loop output impedance for stable high-capacitance interfacing, integrated RFI/EMI filtering, and extended –40°C to 125°C temperature range compliance.
Technical Context
The TLV9002IDR implements a scalable CMOS architecture designed specifically for low-voltage operation with rail-to-rail input common-mode range extending 100 mV beyond rails and rail-to-rail output swing within 10 mV of supply rails. Its unity-gain stable design eliminates external compensation requirements across all gain configurations.
Internal EMI/RFI rejection filtering suppresses high-frequency interference without external components, while the resistive open-loop output impedance enables stable operation into ≥500 pF capacitive loads-critical for driving long traces or ADC input capacitance in sensor front-ends.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9002IPWR | Same electrical specs; 8-pin TSSOP (PW) package (3.00 mm × 4.40 mm) instead of SOIC (D) | Better thermal performance in high-density layouts due to smaller footprint and exposed pad option | Select TLV9002IPWR when board space is constrained or thermal dissipation exceeds SOIC limits |
| LMV358IDR | Higher quiescent current (150 µA/ch), lower bandwidth (1 MHz same), wider offset (±3 mV), no integrated EMI filter | Limited suitability for ultra-low-power or EMI-prone environments like wearable RF co-location | Choose LMV358IDR only if legacy compatibility or cost sensitivity outweighs low-power and noise advantages |
Compared with TLV9002IDR, TLV9002IPWR offers identical performance in a smaller TSSOP package ideal for space-constrained designs, while LMV358IDR trades off power efficiency and EMI robustness for broader legacy support-making TLV9002IDR optimal for next-generation battery-powered and noise-sensitive applications.

FAQ
What is the maximum capacitive load the TLV9002IDR can drive stably?
The TLV9002IDR is characterized to drive up to 500 pF capacitive load stably without external compensation, thanks to its resistive open-loop output impedance. This specification is verified per TI's SBOS833R datasheet Section 7.10 and enables direct interfacing with SAR ADC inputs and long PCB traces in sensor signal chains. The TLV9002IDR maintains phase margin >45° under this condition.
Does the TLV9002IDR support single-supply operation?
Yes, the TLV9002IDR supports true single-supply operation from 1.8 V to 5.5 V, with rail-to-rail input common-mode range extending 100 mV beyond both supply rails and rail-to-rail output swing within 10 mV of V– and V+. This allows ground-referenced sensor interfaces-such as low-side current shunts-without level-shifting circuitry, as confirmed in the Electrical Characteristics table of the TLV9002IDR datasheet.
What is the input offset voltage specification for TLV9002IDR over temperature?
The TLV9002IDR has a maximum input offset voltage of ±0.4 mV at room temperature (25°C), with a typical drift of ±0.15 µV/°C over the full –40°C to 125°C operating range. This low drift ensures minimal baseline error in precision applications like smoke detector ionization current measurement, where long-term stability directly impacts false-alarm rate.
Is the TLV9002IDR pin-compatible with other devices in the TLV900x family?
No-the TLV9002IDR (8-pin SOIC) shares pinout compatibility only with other TLV9002 variants in SOIC, VSSOP, TSSOP, SOT-23, and WSON packages, as defined in Table 6-3 of the SBOS833R datasheet. It is not pin-compatible with TLV9001 (5-pin) or TLV9004 (14-/16-pin) packages due to differing channel count and pin assignments.
What ESD protection does the TLV9002IDR provide?
The TLV9002IDR provides ±2000 V HBM (Human Body Model) and ±1500 V CDM (Charged Device Model) ESD ratings per JEDEC standards JS-001 and JESD22-C101. These values apply to the SOIC (D) package variant and ensure robust handling during automated assembly and field operation in industrial environments, as specified in Section 7.2 of the official datasheet.
