Product details
Overview
THS4012CDR from Texas Instruments is a dual-channel, voltage-feedback high-speed operational amplifier optimized for precision video and wideband signal conditioning. It delivers 290-MHz bandwidth (G = 1), 310-V/µs slew rate, and 37-ns 0.1% settling time, operating from ±4.5 V to ±16 V supplies. It drives 110 mA into 20 Ω loads and achieves –80 dBc THD at 1 MHz with 7.5 nV/√Hz input voltage noise - ideal for broadcast-quality analog video routing and high-fidelity data acquisition front-ends.
For engineers reviewing the THS4012CDR datasheet, THS4012CDR pinout, THS4012CDR application, or THS4012CDR equivalent, key selection considerations include its dual-channel SOIC-8 layout, ±15 V operation capability, low differential gain/phase error (0.006%/0.01°), and thermal performance in D-package with 167°C/W junction-to-ambient rating.
Technical Context
The THS4012CDR employs a dielectrically isolated complementary bipolar process enabling simultaneous high bandwidth, fast settling, and low distortion. Its voltage-feedback architecture supports stable unity-gain operation with internal compensation tuned for minimal peaking in noninverting configurations.
It features rail-to-rail output swing (±13.5 V into 1 kΩ at ±15 V supply), 82 dB CMRR at 25°C, and 12 Ω open-loop output impedance - enabling direct drive of 75 Ω video lines with series termination. Input common-mode range extends to ±14.1 V at ±15 V supply, supporting DC-coupled signal paths in professional video infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1: enables full HD baseband video amplification without attenuation up to 200 MHz. |
| Slew Rate | 310 V/µs: supports clean reproduction of fast transients in pulse-amplifier and ADC driver applications. |
| Settling Time (0.1%) | 37 ns: ensures accurate sampling in high-speed data acquisition systems with >10 MSPS throughput. |
| Total Harmonic Distortion | –80 dBc at 1 MHz, RL = 150 Ω: meets broadcast-grade NTSC/PAL differential gain/phase specs (0.006%/0.01°). |
| Supply Voltage Range | ±4.5 V to ±16 V: compatible with legacy ±5 V, ±12 V, and ±15 V industrial and test equipment rails. |
| Output Current Drive | 110 mA (typical): directly drives two 75 Ω video loads or one 50 Ω RF line with proper series termination. |
| Input Voltage Noise | 7.5 nV/√Hz at 10 kHz: preserves SNR in low-level signal amplification stages before digitization. |
Pinout & Package
THS4012CDR is housed in an 8-pin SOIC (D) package with standard pin spacing (1.27 mm pitch) and exposed pad not present - distinct from the thermally enhanced DGN variant. Pin 1 is marked by a beveled corner or dot; device orientation follows TI's top-view convention with pin 1 at top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A; requires 20 Ω series resistor when driving >10 pF capacitive loads to prevent ringing. |
| 2 | IN− A | Inverting input of channel A; shortest possible PCB trace required to minimize stray capacitance and maintain stability. |
| 3 | IN+ A | Noninverting input of channel A; suitable for single-pole RC filtering (e.g., 100 Ω + 100 pF) to limit noise bandwidth. |
| 4 | VCC− | Negative supply rail; must be decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin. |
| 5 | VCC+ | Positive supply rail; decoupling identical to VCC−; shared supply traces must avoid coupling between channels. |
| 6 | OUT B | Output of independent channel B; electrically isolated from channel A - crosstalk < –80 dB at 1 MHz. |
| 7 | IN− B | Inverting input of channel B; layout symmetry recommended to match channel A for balanced dual-path designs. |
| 8 | IN+ B | Noninverting input of channel B; offset nulling pins (1 & 8) support external potentiometer for fine DC calibration. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent amplifiers | Enables compact side-by-side signal paths (e.g., Y/C separation or differential receiver pairs) without inter-channel interference. |
| 0.1-dB bandwidth of 70 MHz | Preserves amplitude flatness across entire NTSC/PAL luminance band (0–5.5 MHz) with margin for harmonics. |
| Low 0.006% differential gain error | Eliminates color saturation shifts in composite video distribution; verified at ±15 V supply with 150 Ω load. |
| Offset nulling capability | Pins 1 and 8 accept 10-kΩ potentiometer wiper to VCC−, enabling sub-mV DC offset correction in precision instrumentation. |
| Thermal shutdown protection | Activates at TJ ≥ 150°C per absolute maximum ratings, preventing latch-up during sustained overload conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4012IDR | Same silicon, extended temperature range (–40°C to +85°C) vs. THS4012CDR (0°C to +70°C); identical electrical specs. | Required for industrial environments with ambient extremes; not rated for commercial-only deployments. | Select THS4012IDR when operating outside 0–70°C or requiring automotive-grade reliability screening. |
| LMH6702MA/NOPB | Higher 1.8 GHz GBW but higher 10.5 nV/√Hz noise; no offset null pins; SOIC-8 package with different pinout (no IN+/IN− symmetry). | Better for RF IF amplification; unsuitable for video where differential gain/phase specs are mandatory. | Choose LMH6702MA/NOPB only when bandwidth >1 GHz is critical and video fidelity is secondary. |
Compared with THS4012CDR, THS4012IDR offers identical performance with wider temperature tolerance, while LMH6702MA/NOPB trades video-optimized linearity for raw speed - making THS4012CDR the preferred choice for broadcast, medical imaging, and precision test equipment where distortion and timing accuracy are non-negotiable.

FAQ
What is the maximum supply voltage for THS4012CDR?
The THS4012CDR supports dual-supply operation from ±4.5 V to ±16 V, with absolute maximum ratings of ±16.5 V. Operation beyond ±16 V risks permanent damage. For single-supply use, it accepts 9 V to 32 V between VCC+ and VCC− pins, validated per TI's SLOS216E datasheet Section 6.1.
Does THS4012CDR support DC-coupled inputs?
Yes, THS4012CDR supports DC-coupled inputs with a common-mode input voltage range of ±14.1 V at ±15 V supply (±4.3 V at ±5 V). This allows direct connection of sensors or DAC outputs without AC coupling capacitors - essential for precision instrumentation and video sync signal handling.
Can THS4012CDR drive 75 Ω video loads directly?
THS4012CDR can drive 75 Ω loads when configured with a 75 Ω series resistor at the output (per Figure 27 in SLOS216E), isolating capacitive effects and matching source impedance. Without this resistor, instability may occur due to phase margin degradation - confirmed in TI's Application Information section on capacitive load driving.
What is the purpose of pins 1 and 8 on THS4012CDR?
Pins 1 (OUT A) and 8 (IN+ B) serve as offset null terminals for the THS4012CDR. A 10-kΩ potentiometer is connected between them, with its wiper tied to VCC−, enabling manual adjustment of input offset voltage down to sub-millivolt levels - critical for precision DC-coupled applications like medical sensor interfaces.
How does THS4012CDR compare to THS4011 in terms of channel count and pin compatibility?
THS4012CDR is a dual-channel amplifier in SOIC-8, while THS4011CDR is its single-channel counterpart in SOIC-8. They share identical pin functions per channel (e.g., IN+, IN−, OUT, VCC±), but THS4012CDR integrates both channels in one package - eliminating board space and cost versus using two THS4011CDRs, with verified channel isolation >80 dB.
