Product details
Overview
TLC084AIPWPR from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It features rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 125 µA/channel shutdown current, and is housed in a thermally enhanced 20-pin TSSOP (PWP) package for high-density industrial signal conditioning.
For engineers reviewing the TLC084AIPWPR datasheet, TLC084AIPWPR pinout, TLC084AIPWPR application, or TLC084AIPWPR equivalent, key selection criteria include its guaranteed 2000 µV max input offset voltage (A-grade), 8.5 nV/√Hz input noise, and ability to drive heavy loads without external buffers in audio line drivers, sensor front-ends, and programmable logic controller analog I/O modules.
Technical Context
The TLC084AIPWPR implements a CMOS-input/bipolar-output BiMOS architecture that enables simultaneous high impedance (>1 GΩ differential input resistance), low noise, and robust output stage current delivery. Its internal design supports true single-supply operation with VICR extending to ground and output swing within 0.5 V of rails under 50 mA load.
Each channel integrates independent shutdown control (pins 5 and 10), eliminating crosstalk during power gating. The device operates across –40°C to +125°C and maintains stable phase margin (≥37° at 50 pF load) without external compensation, enabling direct use in unity-gain stable configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower bandwidth (6.4 MHz), lower output drive (±30 mA), no shutdown pins, 1.5 V to 6 V supply. | Better suited for low-voltage battery-powered portable instruments; lacks industrial temp range and high-current capability. | Select when supply is ≤6 V and load current <30 mA; avoid for 12 V industrial systems requiring robust drive. |
| OPA4340UA | Higher precision (125 µV max VIO), rail-to-rail output, but only 1 MHz bandwidth and ±20 mA drive. | Ideal for high-accuracy DC measurement front-ends where speed is secondary to offset stability. | Choose for µV-level DC accuracy in data loggers; not viable for audio or fast feedback loops requiring >5 MHz BW. |
Compared with TLV2464IDR and OPA4340UA, the TLC084AIPWPR uniquely balances wide bandwidth, high output current, extended temperature range, and integrated shutdown-making it the only option among the three qualified for demanding 12 V industrial motor control and audio line-driving applications.

FAQ
What is the maximum supply voltage rating for the TLC084AIPWPR?
The TLC084AIPWPR has an absolute maximum supply voltage (VDD) rating of 17 V. Operation is specified across 4.5 V to 16 V for reliable performance; exceeding 16 V may cause permanent damage or parametric shift. This rating applies to the entire device, not per channel, and must be observed even during transient conditions.
Does the TLC084AIPWPR support rail-to-rail output swing?
The TLC084AIPWPR does not provide rail-to-rail output swing. Its output voltage swing is typically within 0.5 V of the negative rail (GND) and within 1.5 V of the positive rail (VDD) under 50 mA load. At lighter loads (1 mA), it achieves ~0.2 V from GND and ~0.3 V from VDD - sufficient for many industrial interfaces but not for true rail-to-rail applications.
How is shutdown controlled on the TLC084AIPWPR?
Shutdown on the TLC084AIPWPR is controlled via two dedicated active-low pins: pin 5 controls channels 1 and 2, and pin 10 controls channels 3 and 4. Driving either pin below 0.8 V places its associated pair into ultralow-power shutdown (125 µA/channel), while pulling above 2 V enables normal operation. Both pins must be driven independently; no internal logic ties them together.
What is the guaranteed input offset voltage specification for TLC084AIPWPR over temperature?
The TLC084AIPWPR (A-grade) guarantees a maximum input offset voltage of 2000 µV across the full operating temperature range of –40°C to +125°C, as specified in the Electrical Characteristics table for VDD = 5 V and 12 V. This is tighter than the standard-grade TLC084 (3000 µV max) and ensures predictable DC accuracy in harsh thermal environments.
Can the TLC084AIPWPR drive capacitive loads without oscillation?
Yes - the TLC084AIPWPR is unity-gain stable and maintains ≥37° phase margin with up to 50 pF capacitive load at VDD = 12 V (per Typical Characteristics Figure 19). For loads >50 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between output and capacitance to preserve stability, especially in high-impedance sensor buffer configurations.
