Texas Instruments THS3001HVIDGN

Overview

THS3001HVIDGN from Texas Instruments is a high-speed current-feedback operational amplifier designed for large-signal, wideband analog signal conditioning in demanding communication and video systems. It delivers 420MHz small-signal bandwidth (G = 1), 6500V/μs slew rate at ±15V supply, 40ns settling time to 0.1%, ≤3mV input offset voltage, and –96dBc THD at 1MHz - enabling use as a buffer for ultra-fast ADC/DAC interfaces or high-fidelity video line drivers.

For engineers reviewing the THS3001HVIDGN datasheet, THS3001HVIDGN pinout, THS3001HVIDGN application, or THS3001HVIDGN equivalent, key selection criteria include its current-feedback architecture's gain-bandwidth independence, thermal performance in HVSSOP-8 (R_θJA = 56.9°C/W), low distortion at 10MHz, and compatibility with ±4.5V to ±16V dual supplies or 9V–32V single supplies.

Technical Context

The THS3001HVIDGN implements a dielectrically isolated complementary bipolar (HVBiCOM) process with GHz f_T NPN/PNP transistors, enabling its current-feedback topology where bandwidth is set primarily by feedback resistor value-not closed-loop gain. Its transresistance architecture decouples gain-setting from bandwidth control, allowing stable operation across gains of –5 to +1000 with appropriate R_F/R_G selection.

This device operates in a single functional mode supporting both split-supply (±4.5V to ±16V) and single-supply (9V–32V) configurations. Input common-mode range extends to ±13.2V at ±15V supply, output swing reaches ±12.8V into 1kΩ, and open-loop transresistance is 2.4MΩ - confirming high loop gain and precision DC performance alongside RF-grade transient response.

FAQ

What is the maximum operating temperature range for the THS3001HVIDGN?

The THS3001HVIDGN is rated for continuous operation from –40°C to +85°C ambient temperature. Its junction temperature must not exceed 125°C for long-term reliability, and absolute maximum junction temperature is 150°C. Thermal design using the HVSSOP-8 package's R_θJA = 56.9°C/W and R_θJC(bot) = 12.5°C/W is critical to maintain this limit under full output load.

Can the THS3001HVIDGN be used with single-supply operation?

Yes, the THS3001HVIDGN supports single-supply operation from 9V to 32V. When operated this way, the IN+ input must be biased within the common-mode range (e.g., V_CC/2), and output swing is centered accordingly. The device's rail-to-rail output capability is not claimed; typical swing is ±12.8V into 1kΩ at ±15V, so single-supply headroom must be verified per application.

What feedback resistor value is recommended for G = 2 configuration with ±15V supply?

For a noninverting gain of 2 with ±15V supply, TI recommends R_F = 680Ω and R_G = 680Ω. This combination delivers optimized bandwidth (385MHz), phase margin, and distortion (–96dBc at 1MHz). Using 1% tolerance metal-film resistors is essential to maintain consistent performance across production units.

How does the THS3001HVIDGN's current-feedback architecture affect stability versus voltage-feedback op amps?

Unlike voltage-feedback amplifiers, the THS3001HVIDGN's bandwidth depends primarily on feedback resistor value, not closed-loop gain. Stability is maintained by selecting R_F per TI's table (e.g., 680Ω for G = 2), avoiding excessive capacitance at the inverting input, and using proper power supply decoupling. Its current-feedback topology inherently avoids gain-bandwidth trade-offs that destabilize VFB designs at high frequencies.

Is an evaluation module available for the THS3001HVIDGN?

Yes, Texas Instruments offers the THS3001EVM evaluation module, which supports both D (SOIC-8) and DGN (HVSSOP-8) packages including THS3001HVIDGN. The EVM provides configurable gain settings, SMA input/output connectors, and provisions for bypass capacitor optimization - enabling rapid prototyping of high-speed signal paths without custom PCB design.
