Product details
Overview
THS4032MDGNREP from Texas Instruments is a dual-channel, ultralow-noise, high-speed voltage-feedback operational amplifier designed for precision analog signal conditioning in defense, aerospace, and medical systems. It delivers 100-MHz bandwidth (G = 2), 100-V/µs slew rate, 1.6-nV/√Hz input voltage noise, ±5 V to ±15 V dual-supply operation, and 90-mA output drive per channel.
For engineers reviewing the THS4032MDGNREP datasheet, THS4032MDGNREP pinout, THS4032MDGNREP application, or THS4032MDGNREP equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases in imaging and ADC buffering, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The THS4032MDGNREP employs a voltage-feedback architecture with unity-gain stability and 275-MHz small-signal bandwidth. Its internal design supports low distortion (–96 dBc THD at 1 MHz, RL = 1 kΩ) and fast settling (60 ns to 0.1% at ±15 V), enabling high-fidelity signal amplification in wideband applications.
It features rail-to-rail output swing capability (±12.9 V into 1 kΩ at ±15 V), high CMRR (95 dB typical), and robust thermal performance enabled by the MSOP-PowerPAD™ package - optimized for high-power-density layouts requiring efficient heat dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 100 MHz at G = 2 (±15 V); enables baseband video and IF signal amplification up to 100 MHz |
| Slew Rate | 100 V/µs (±15 V); supports clean amplification of fast transient signals without slewing distortion |
| Voltage Noise | 1.6 nV/√Hz (f > 10 kHz); critical for preserving SNR in low-level sensor and imaging front-ends |
| THD | –96 dBc at f = 1 MHz, RL = 1 kΩ; ensures minimal harmonic contamination in precision ADC driver stages |
| Output Drive | 90 mA (typical, ±15 V); drives heavy loads including 150-Ω video lines and multiplexed ADC inputs |
| Input Offset Voltage | 0.5 mV (typical, ±15 V); reduces DC error accumulation in multi-stage gain blocks |
| Supply Range | ±4.5 V to ±16 V dual supply; accommodates legacy ±5 V and high-dynamic-range ±15 V systems |
Pinout & Package
The THS4032MDGNREP is housed in an 8-pin MSOP-PowerPAD™ (DGN) package with exposed thermal pad for enhanced power dissipation. Pin 1 is marked with a dot; PowerPAD™ is soldered to PCB ground plane for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A; connects directly to load or next stage with minimal trace inductance |
| 2 | IN− A | Inverting input for channel A; requires matched layout to IN+ A to minimize common-mode rejection degradation |
| 3 | IN+ A | Non-inverting input for channel A; high-impedance node sensitive to parasitic capacitance |
| 4 | VCC− | Negative supply rail; must be decoupled locally with 0.1 µF ceramic + bulk capacitor |
| 5 | VCC+ | Positive supply rail; shared between both channels; requires independent decoupling from VCC− |
| 6 | OUT B | Inverting amplifier output channel B; electrically isolated from OUT A but shares supply rails |
| 7 | IN− B | Inverting input for channel B; layout symmetry with channel A improves crosstalk performance (–70 dB @ 10 MHz) |
| 8 | IN+ B | Non-inverting input for channel B; referenced to same common-mode range as IN+ A (±14.3 V @ ±15 V) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032D | Same die, SOIC-8 package; θJA = 167°C/W vs. DGN's 58.4°C/W; no PowerPAD™ thermal pad | Limited to lower ambient temperatures or reduced output current; unsuitable for sustained 90-mA loads in compact enclosures | Select THS4032D only when board space permits larger SOIC footprint and thermal margin exceeds 25°C |

FAQ
What is the maximum junction temperature specification for THS4032MDGNREP during continuous operation?
The THS4032MDGNREP has a maximum junction temperature of 130°C for continuous operation to ensure long-term reliability. This limit is defined by package constraints and applies under conditions where power dissipation remains within the rated 1.8 W (at TA = 25°C). Exceeding 130°C may reduce device lifetime; thermal design must maintain TJ ≤ 130°C using the DGN package's θJC = 4.7°C/W path to PCB ground.
Does THS4032MDGNREP support single-supply operation, and what is its minimum recommended supply voltage?
Yes, THS4032MDGNREP supports single-supply operation with a minimum total supply voltage of 9 V (e.g., 0 V to +9 V). The recommended operating range is 9 V to 32 V for single supply, and ±4.5 V to ±16 V for dual supply. Input common-mode range extends to within 1.5 V of each rail, enabling direct interfacing with 3.3-V or 5-V logic-controlled systems when biased appropriately.
How does the PowerPAD™ feature in the DGN package improve thermal performance of THS4032MDGNREP?
The PowerPAD™ in the THS4032MDGNREP's MSOP package is an exposed copper thermal pad soldered directly to the PCB ground plane. It reduces thermal resistance from junction to case (θJC) to 4.7°C/W - over 3× lower than standard SOIC - enabling 1.8 W continuous power dissipation at TJ = 130°C. This allows sustained 90-mA output drive in compact, high-density layouts without external heatsinks.
What is the typical input offset voltage drift over temperature for THS4032MDGNREP?
The THS4032MDGNREP exhibits a typical input offset voltage drift of 2 µV/°C across its full operating range of –55°C to +125°C. This low drift ensures minimal DC error accumulation in precision gain stages used in medical instrumentation and test equipment, where baseline stability over wide ambient variations is essential for measurement accuracy.
Can THS4032MDGNREP drive a 150-Ω load at full output swing, and what is the guaranteed performance?
Yes, THS4032MDGNREP is specified to drive a 150-Ω load with ±12 V output swing (min) at ±15 V supply, delivering up to 90 mA (typical) output current. At ±5 V supply, it guarantees ±3 V swing into 250 Ω. Performance is validated per TI's SLOS610 datasheet, including THD = –81 dBc (RL = 150 Ω, f = 1 MHz), confirming suitability for broadcast video and high-speed communication line driving.
