Product details
Overview
TLV9004IDYYR 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 wearable devices and smoke detectors.
For engineers reviewing the TLV9004IDYYR datasheet, TLV9004IDYYR pinout, TLV9004IDYYR application, or TLV9004IDYYR 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, –40°C to 125°C extended temperature range, and shutdown capability in S-variants (not present in TLV9004IDYYR).
Technical Context
The TLV9004IDYYR uses scalable CMOS process technology to achieve low input bias current (5 pA) and low broadband noise (27 nV/√Hz) while maintaining unity-gain stability. Its resistive open-loop output impedance simplifies compensation with capacitive loads up to 500 pF-critical for driving long traces or ADC input filters without external isolation resistors.
This device 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 no phase reversal during overdrive-ensuring reliable behavior in fault conditions such as sensor saturation or power sequencing transients.

|---|---|---|
| 1 | OUT1 | Output of channel 1 - rail-to-rail swing, capable of sourcing/sinking ±25 mA (typical) |
| 2 | IN1– | Inverting input of channel 1 - high-impedance node; sensitive to layout-induced leakage and EMI |
| 3 | IN1+ | Noninverting input of channel 1 - referenced to system ground or bias network for single-supply operation |
| 4 | V+ | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004IDR | Same electrical specs; SOIC-14 package (8.65 mm × 3.91 mm) - 4× larger footprint than DYY | Better thermal dissipation and hand-solderability; unsuitable for ultra-dense wearable PCBs | Select TLV9004IDR for prototyping, industrial control boards, or where rework access is required. |
| LMV324DR | Higher quiescent current (130 µA/ch), wider offset (±3 mV), lower bandwidth (1.4 MHz), no EMI filter | Lacks RFI rejection and extended temp rating - not recommended for safety-critical smoke detectors or automotive HVAC | Choose LMV324DR only for non-safety, cost-driven consumer appliances with 3.3-V/5-V supplies and relaxed accuracy needs. |
Compared with TLV9004IDYYR, TLV9004IDR offers mechanical robustness and thermal margin at the expense of size, while LMV324DR trades precision, noise, and EMI immunity for legacy compatibility and broader distributor stock - making TLV9004IDYYR the optimal choice for miniaturized, battery-powered, and safety-relevant designs.

FAQ
What is the maximum capacitive load the TLV9004IDYYR can drive stably?
The TLV9004IDYYR is characterized to drive up to 500 pF capacitively without external compensation. This capability stems from its resistive open-loop output impedance, which avoids peaking and oscillation seen in conventional op amps. For loads exceeding 500 pF, TI recommends verifying stability via simulation or bench testing using the specific PCB layout and load configuration. The TLV9004IDYYR datasheet confirms this value in Section 7.10 Electrical Characteristics.
Does the TLV9004IDYYR include a shutdown pin?
No, the TLV9004IDYYR does not include a shutdown function. Shutdown capability is only available in the 'S' variants (e.g., TLV9004S), which feature dedicated SHDN12 and SHDN34 pins. The TLV9004IDYYR is a standard quad op amp with continuous operation - ideal for applications requiring always-on signal conditioning without control logic overhead.
What is the input common-mode voltage range of the TLV9004IDYYR?
The TLV9004IDYYR supports rail-to-rail input, meaning its common-mode voltage range extends from V– – 0.1 V to V+ + 0.1 V (per Absolute Maximum Ratings). In practice, it operates linearly from V– to V+, enabling direct interfacing with ground-referenced sensors and single-supply systems powered by 1.8 V or higher. This is confirmed in the "Features" section and Section 8.3 of the TLV9004IDYYR datasheet.
Can the TLV9004IDYYR operate from a 1.8-V single supply?
Yes, the TLV9004IDYYR is fully specified for operation from 1.8 V to 5.5 V single-supply or split-supply configurations. At 1.8 V, it maintains rail-to-rail input/output swing, 1 MHz bandwidth, and 60 µA per channel quiescent current. This makes TLV9004IDYYR suitable for direct integration with energy-harvesting circuits and coin-cell–powered devices where supply headroom is minimal.
Is the TLV9004IDYYR pin-compatible with other TLV900x family members?
No, the TLV9004IDYYR (14-pin SOT-23) is not pin-compatible with other TLV900x packages. Its pinout differs from SOIC-14 (TLV9004IDR), TSSOP-14 (TLV9004IPWR), and WQFN-16 (TLV9004IRTER). Pin mapping is unique to the DYY package - verified in Table 6-5 of the TLV9004IDYYR datasheet. Interchangeability requires PCB redesign unless using identical DYY-packaged variants.
