Product details
Overview
THS4041IDRQ1 from Texas Instruments is a single-channel, automotive-qualified, high-speed voltage-feedback amplifier optimized for driving capacitive loads up to 1000 pF without external compensation. It delivers 165 MHz bandwidth (−3 dB, CL = 0 pF), 400 V/µs slew rate, and ±100 mA output drive into 20 Ω. Its unity-gain stability, 0.01% differential gain error, and ±5 V to ±15 V dual-supply operation make it ideal for video line driving and ADC buffering in automotive camera modules.
For engineers reviewing the THS4041IDRQ1 datasheet, THS4041IDRQ1 pinout, THS4041IDRQ1 application, or THS4041IDRQ1 equivalent, key selection criteria include capacitive-load stability, video distortion performance (THD = −89 dBc at 1 MHz, RL = 1 kΩ), differential phase accuracy (0.01°), and AEC-Q100 qualification for automotive signal conditioning.
Technical Context
The THS4041IDRQ1 employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth and low distortion. Its internal C-stable architecture dynamically adjusts compensation based on capacitive load magnitude, preserving phase margin across CL = 0–1000 pF.
This amplifier supports both inverting and noninverting configurations at all gains, with dedicated null pins (1, 8) for offset trimming. It features rail-to-rail input common-mode range (±14.3 V at ±15 V supply) and maintains 70–90 dB CMRR over 100 kHz–10 MHz.

| Output Drive | ±100 mA into 20 Ω - drives heavy video loads or multiple 75-Ω lines simultaneously |
| Differential Gain Error | 0.01% at NTSC, ±15 V - preserves color fidelity in automotive rear-view camera systems |
| THD | −89 dBc at 1 MHz, RL = 1 kΩ - ensures low harmonic distortion for precision analog front-ends |

Pinout & Package
THS4041IDRQ1 is housed in an 8-pin SOIC (D) package with exposed pad not electrically connected. Thermal resistance θJA = 215°C/W (JEDEC Low-K PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null Input | Connects to wiper of 10-kΩ potentiometer for manual input offset adjustment |
| 2 (IN−) | Inverting Input | High-impedance node (1 MΩ) for feedback network connection in inverting configurations |
| 3 (IN+) | Noninverting Input | Common-mode range extends to ±14.3 V at ±15 V supply - supports DC-coupled sensor interfaces |
| 4 (VCC−) | Negative Supply Rail | Must be decoupled with 0.1 µF ceramic capacitor close to pin for high-frequency stability |
| 5 (NC) | No Internal Connection | Not bonded; leave unconnected and unpopulated on PCB |
| 6 (OUT) | Amplified Output | Capable of sourcing/sinking ±100 mA; series isolation resistor (≥20 Ω) recommended for >100 pF loads |
| 7 (VCC+) | Positive Supply Rail | Requires local 0.1 µF ceramic decoupling; PSRR = 84 dB at DC minimizes supply noise coupling |
| 8 (NULL) | Offset Null Reference | Connected to VCC− for symmetric nulling; enables sub-mV offset correction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Higher slew rate (2000 V/µs), lower bandwidth (210 MHz), no AEC-Q100 qualification | Targeted at non-automotive test equipment; lacks automotive temp range and qualification | Select THS3091DR only for non-automotive designs requiring faster edge rates and accepting wider supply range (±5 V to ±15 V same) |
| LMH6702MA/NOPB | Wider bandwidth (1.8 GHz), higher supply current (12.5 mA), no offset null pins | Used in RF and wideband communications; lacks video-specific linearity specs and automotive qualification | Choose LMH6702MA/NOPB for >500-MHz small-signal applications where differential gain/phase specs are irrelevant |
Compared with THS3091DR and LMH6702MA/NOPB, THS4041IDRQ1 uniquely combines AEC-Q100 qualification, C-stable capacitive-load drive, and video-grade linearity-making it the only drop-in solution for automotive camera signal chains requiring guaranteed stability and color fidelity across temperature.

FAQ
What is the maximum capacitive load the THS4041IDRQ1 can drive without external compensation?
The THS4041IDRQ1 is specified to drive up to 1000 pF without external compensation while maintaining stability, as verified by its C-stable architecture and measured overshoot data (Figure 24). At CL = 1000 pF, output overshoot remains below 10% for 1-V and 5-V steps under ±15 V supply. For loads exceeding 1000 pF, a series isolation resistor ≥20 Ω is recommended per Figure 65 in the THS4041IDRQ1 datasheet.
Does the THS4041IDRQ1 support single-supply operation?
Yes, the THS4041IDRQ1 supports single-supply operation from 9 V to 32 V, as stated in the Recommended Operating Conditions table (page 3). However, its input common-mode range and output swing are optimized for dual-supply use (±4.5 V to ±16.5 V); single-supply applications require careful biasing of the IN+ pin and verification of output headroom using the VO vs. VCC curves (Figure 47).
How does the THS4041IDRQ1 achieve unity-gain stability with high bandwidth?
The THS4041IDRQ1 achieves unity-gain stability through internal frequency compensation tailored to its dielectrically isolated complementary bipolar process. This allows 165-MHz bandwidth while maintaining sufficient phase margin (>45°) at G = +1, as confirmed by open-loop gain/phase plots (Figure 3). The design avoids the bandwidth sacrifice typical of traditional dominant-pole compensation.
What is the purpose of Pins 1 and 8 on the THS4041IDRQ1?
Pins 1 and 8 are offset null terminals used to adjust input offset voltage via an external potentiometer (10 kΩ typical, wiper to VCC−), as shown in Figure 66. This feature enables trimming of VOS down to <1 mV in precision applications - critical for DC-coupled video or sensor signal paths where offset drift affects baseline accuracy.
Is the THS4041IDRQ1 pin-compatible with other THS404x variants?
Yes, the THS4041IDRQ1 shares identical 8-pin SOIC (D) pinout and electrical behavior with THS4042 (dual) and THS4043 (quad) variants, as confirmed by the functional block diagram (Figure 1) and package drawings referenced in the datasheet. All THS404x devices use the same pin mapping for IN+, IN−, OUT, VCC+, VCC−, and NULL pins, enabling scalable design reuse.
