Product details
Overview
THS4041IDRG4Q1 from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier qualified for automotive applications. It delivers 165 MHz bandwidth (−3 dB, CL = 0 pF), 400 V/µs slew rate, and unity-gain stability while driving any capacitive load up to 1000 pF. Its low 0.01% differential gain error and 0.01° differential phase error make it ideal for precision video line driving and ADC buffering in ±5 V to ±15 V systems.
For engineers reviewing the THS4041IDRG4Q1 datasheet, THS4041IDRG4Q1 pinout, THS4041IDRG4Q1 application, or THS4041IDRG4Q1 equivalent, key selection criteria include capacitive-load stability, wide supply range compatibility, video distortion performance, and automotive-grade temperature operation (−40°C to +85°C).
Technical Context
The THS4041IDRG4Q1 uses a dielectrically isolated complementary bipolar process enabling GHz fT transistors, supporting high-speed voltage-feedback architecture with internal C-stable compensation. This compensation dynamically adjusts the dominant pole based on detected capacitive load, maintaining stability across 0–1000 pF without external components.
It operates in both inverting and noninverting configurations at all gains, with optimized unity-gain response achieved using a 200 Ω feedback resistor. The device features dedicated null pins (1 and 8) for input offset adjustment and supports rail-to-rail output swing into 150 Ω loads under ±15 V supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4031IDRQ1 | Lower 100 MHz bandwidth, 250 V/µs slew rate, same SOIC-8 package and pinout | Targeted for cost-sensitive video applications where 165 MHz is not required | Select when system bandwidth requirement is ≤100 MHz and power consumption must be minimized (ICC = 7.5 mA vs. 9.5 mA) |
| LMH6702MA/NOPB | Higher 1.8 GHz GBW, 3000 V/µs slew rate, but not unity-gain stable and requires external compensation | Used in RF IF amplification or ultra-high-speed test equipment-not suitable for direct video line driving | Choose only for closed-loop gains ≥5 and when board space allows for compensation network design |
Compared with THS4041IDRG4Q1, THS4031IDRQ1 offers lower bandwidth and power for simpler video paths, while LMH6702MA/NOPB provides extreme speed at the cost of stability complexity and higher supply current-neither is pin-compatible, and both require layout and compensation revalidation.

FAQ
What is the maximum capacitive load the THS4041IDRG4Q1 can drive while remaining stable?
The THS4041IDRG4Q1 remains unity-gain stable with capacitive loads up to 1000 pF without external compensation, thanks to its internal C-stable architecture. At 1000 pF, typical overshoot is <15% for a 5-V step, and bandwidth reduces to 35 MHz (−3 dB). For loads >100 pF, a 20 Ω series isolation resistor at the output is recommended to suppress peaking and ensure optimal transient response in the THS4041IDRG4Q1 design.
Does the THS4041IDRG4Q1 support single-supply operation?
Yes, the THS4041IDRG4Q1 supports single-supply operation from 9 V to 33 V. When operated from a +12 V single supply, the common-mode input voltage range extends from 3.8 V to 10.3 V (typ), and the output can swing within 1.5 V of each rail into 1 kΩ. For rail-to-rail input/output performance, external level-shifting or biasing is required-the THS4041IDRG4Q1 itself is not a rail-to-rail input/output op-amp.
How does the THS4041IDRG4Q1 achieve automotive qualification?
The THS4041IDRG4Q1 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C case temperature, derated to −40°C to +85°C ambient), with 150°C maximum junction temperature rating, enhanced ESD protection (>2 kV HBM), and 100% wafer-level and final-test screening per automotive standards. Its SOIC-8 PowerPAD™ package provides robust thermal performance under sustained load conditions typical in automotive ECUs-critical for long-term reliability of the THS4041IDRG4Q1 in harsh environments.
Can the THS4041IDRG4Q1 replace the THS4041IDRQ1 in existing designs?
Yes, THS4041IDRG4Q1 is a drop-in replacement for THS4041IDRQ1: both share identical electrical specifications, SOIC-8 packaging, pinout, and automotive qualification. The "G4" suffix denotes TI's green (lead-free, RoHS-compliant) packaging standard, while "Q1" confirms AEC-Q100 qualification. No schematic or layout changes are required-only ensure solder profile complies with lead-free reflow specifications for the THS4041IDRG4Q1.
What is the purpose of Pins 1 and 8 on the THS4041IDRG4Q1?
Pins 1 and 8 on the THS4041IDRG4Q1 are dedicated offset null terminals. A 10 kΩ potentiometer is connected between them, with its wiper tied to VCC−, allowing manual trimming of input offset voltage down to <1 mV. This feature is unique to the THS4041IDRG4Q1 among the THS404x family and supports precision DC-coupled applications where auto-zero or chopper amplifiers are unsuitable due to bandwidth limitations.
