Product details
Overview
THS4012CDGN from Texas Instruments is a dual-channel, voltage-feedback high-speed operational amplifier in an 8-pin MSOP PowerPAD™ package. It delivers 290-MHz bandwidth (G = 1), 310-V/µs slew rate, and 37-ns 0.1% settling time, with ±15-V supply capability and 110-mA output drive - enabling precision video signal conditioning and wideband analog front-end buffering in broadcast and test equipment.
For engineers reviewing the THS4012CDGN datasheet, THS4012CDGN pinout, THS4012CDGN application, or THS4012CDGN equivalent, key selection criteria include its dual-channel layout, thermal performance via DGN PowerPAD™, low 7.5-nV/√Hz input voltage noise, and verified 0.006% differential gain error at ±15 V for NTSC video systems.
Technical Context
The THS4012CDGN implements a dielectrically isolated complementary bipolar process architecture optimized for voltage feedback operation, supporting stable unity-gain configurations with internal compensation tuned for bandwidth-slew trade-off. Its dual independent amplifiers share no internal coupling beyond common supply rails, with separate IN+, IN−, and OUT pins per channel.
It operates across ±4.5 V to ±16 V dual supplies or 9 V to 32 V single supply, features rail-to-rail input common-mode range (±14.1 V at ±15 V), and maintains 82-dB CMRR and 75-dB PSRR up to 1 MHz - confirming suitability for mixed-signal acquisition paths where supply rejection and input stage linearity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1: supports full HD video baseband (up to ~150 MHz) with margin for filter roll-off and PCB parasitics. |
| Slew Rate | 310 V/µs at ±15 V: enables clean 20-VPP output at 4.9 MHz full-power bandwidth without slewing distortion. |
| Settling Time (0.1%) | 37 ns: ensures accurate sampling of fast transient signals in digitizer front-ends and pulse amplification. |
| Input Voltage Noise | 7.5 nV/√Hz: preserves SNR in low-level signal chains such as CCD/TDI sensor interfaces and medical imaging preamps. |
| Differential Gain Error | 0.006% at NTSC, ±15 V: meets broadcast-grade video fidelity requirements without external calibration. |
| Output Current Drive | 110 mA (typical): drives two 75-Ω cables simultaneously or heavy capacitive loads with series isolation resistor. |
| Supply Voltage Range | ±4.5 V to ±16 V dual supply: compatible with legacy ±5 V, ±12 V, and ±15 V system rails without level-shifting. |
Pinout & Package
THS4012CDGN uses the thermally enhanced 8-pin MSOP PowerPAD™ (DGN) package with exposed thermal pad on underside - electrically isolated, requiring solder connection to PCB copper for optimal thermal dissipation (2.14 W power rating at TA = 25°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Inverting Input (1IN−) | High-impedance differential input node; requires matched trace length and guarding for >100-MHz stability. |
| 2 | Channel 1 Noninverting Input (1IN+) | High-impedance differential input node; sensitive to stray capacitance - keep trace short and away from noisy nodes. |
| 3 | Channel 1 Output (1OUT) | Low-impedance buffered output; place series resistor (≥20 Ω) before capacitive loads >10 pF to prevent ringing. |
| 4 | Negative Supply (−VCC) | Return path for dual-supply operation; must be decoupled with 0.1-µF ceramic + 6.8-µF tantalum close to pin. |
| 5 | Positive Supply (VCC+) | Power rail for dual-supply operation; same decoupling requirement as −VCC; not internally connected to thermal pad. |
| 6 | Channel 2 Inverting Input (2IN−) | Independent second amplifier input; no internal crosstalk with Channel 1 (–80 dB typical at 1 MHz). |
| 7 | Channel 2 Noninverting Input (2IN+) | Independent second amplifier input; pin-compatible with THS4011 single-channel variant for layout reuse. |
| 8 | Channel 2 Output (2OUT) | Second independent output; supports dual-path signal processing without inter-channel delay skew. |
Key Features

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 |
|---|---|---|---|
| THS4012IDGN | Same electrical specs but rated for –40°C to +85°C industrial temperature range vs. THS4012CDGN's 0°C to +70°C. | Required for outdoor, automotive under-hood, or industrial control environments with extended ambient temperature swings. | Select THS4012IDGN when operating outside 0–70°C; otherwise THS4012CDGN offers cost advantage for commercial-grade equipment. |
| THS4032CDGN | Lower 100-MHz bandwidth, 220-V/µs slew rate, but superior 4.5-nV/√Hz input voltage noise and lower 5.5-mA supply current per channel. | Better suited for low-noise, moderate-bandwidth applications like precision instrumentation or audio line drivers where speed is secondary to SNR. | Choose THS4032CDGN only if bandwidth ≤100 MHz suffices and input noise <5 nV/√Hz is prioritized over slew rate and video fidelity. |
Compared with THS4012IDGN, THS4012CDGN trades extended temperature range for lower cost and same core performance; versus THS4032CDGN, it delivers 2.9× higher bandwidth and 1.4× higher slew rate at the expense of 67% higher input noise - making it the preferred choice for broadcast video and high-speed digitizer front-ends.

FAQ
What is the maximum operating junction temperature for THS4012CDGN?
The THS4012CDGN has a maximum junction temperature (TJ) of 150°C per its Absolute Maximum Ratings table. This limit applies regardless of ambient conditions or package configuration. To maintain reliability, thermal design must ensure actual TJ stays below this value - especially critical in the DGN PowerPAD™ package where proper PCB copper area and via count directly impact steady-state TJ. The THS4012CDGN datasheet provides qJA = 58.4°C/W for the DGN package under specified test conditions.
Does THS4012CDGN support single-supply operation?
Yes, THS4012CDGN supports single-supply operation from 9 V to 32 V, as confirmed in the Recommended Operating Conditions table. When operated from a single supply, the input common-mode range extends from (V− + 3.8 V) to (V+ − 3.8 V) at ±5 V equivalent, and output swing reaches ±3.4 V into 150 Ω. For optimal performance, bias the inputs within the valid common-mode window and use appropriate level-shifting or AC-coupling networks as needed - the THS4012CDGN does not feature rail-to-rail input or output stages.
How is the thermal pad on THS4012CDGN connected?
The exposed thermal pad on the THS4012CDGN (DGN package) is electrically isolated from all pins and must be soldered to a dedicated PCB copper pour connected to ground or another low-impedance thermal plane. TI recommends five 13-mil vias under the pad tied to an internal ground plane with full circumferential plating - not web/spoke connections - to minimize thermal resistance. The pad is not internally connected to any terminal, so incorrect grounding will not cause functional failure but will severely degrade thermal performance and power handling capability of the THS4012CDGN.
Can THS4012CDGN drive a 75-Ω coaxial cable directly?
Yes, THS4012CDGN can drive a 75-Ω coaxial cable directly, provided a 75-Ω series resistor is placed at the output pin (e.g., Pin 3 or Pin 8) to isolate the amplifier from cable capacitance and prevent high-frequency ringing. This matches source impedance, minimizes reflections, and preserves step response integrity. The THS4012CDGN's 110-mA output current rating supports driving one or two 75-Ω loads simultaneously at ±15 V supply, as verified in its Output Current specification (70–110 mA into 20 Ω at ±15 V).
Is THS4012CDGN pin-compatible with THS4011CDGN?
Yes, THS4012CDGN is pin-compatible with THS4011CDGN in the DGN package: both use identical 8-pin MSOP PowerPAD™ footprints and share matching pin functions for IN+, IN−, OUT, and supply rails. The THS4011CDGN is the single-channel version occupying the same physical layout - allowing board designers to use the same land pattern for either device and scale channel count without PCB revision. However, THS4012CDGN provides two independent amplifiers, while THS4011CDGN provides only one.
