What are the key features of TSH330IDT?
- Current-feedback architecture delivering high slew rate and wide bandwidth at fixed gain, ideal for video and RF signal conditioning applications
- Single 5 V supply operation with internal frequency compensation, simplifying power tree design in portable and space-constrained RF systems
- 8-pin SOIC package with 50 dB common-mode rejection ratio for straightforward drop-in integration into wideband amplifier signal chains
What is TSH330IDT used for?
The TSH330IDT is used in high-speed signal chains for video distribution amplifiers, cable driver stages, and IF/RF gain blocks where current-feedback topology provides gain-bandwidth independence not available in conventional voltage-feedback op-amps. Its 5 V single-supply compatibility and internal compensation make it a convenient choice for portable test instruments, communication receiver front ends, and active filter stages. The device is also applied in line drivers and transimpedance amplifier configurations where fast settling and consistent bandwidth at varying gains are critical.

Frequently Asked Questions
Why is a current-feedback amplifier like TSH330IDT preferred over a voltage-feedback op-amp for wideband gain stages?
Current-feedback amplifiers such as the TSH330IDT maintain nearly constant bandwidth regardless of closed-loop gain, unlike voltage-feedback op-amps whose gain-bandwidth product fixes bandwidth as gain increases. This means a TSH330IDT stage set for a gain of 10 can achieve similar –3 dB bandwidth to the same part at unity gain, enabling flat frequency response across multiple gain settings in video or IF signal chains without redesigning the feedback network.
What supply voltage does the TSH330IDT require and what is its input bias current?
The TSH330IDT operates from a single 5 V supply, making it compatible with standard digital system power rails. Its input bias current has a maximum of 55 µA, which is typical for current-feedback topologies due to the low-impedance inverting input architecture. Designers should account for this bias current when selecting feedback resistor values, keeping them in the 500 Ω to 1 kΩ range as recommended to maintain bandwidth and stability.
How should feedback resistor values be chosen for the TSH330IDT to achieve stable operation?
For current-feedback op-amps like the TSH330IDT, the feedback resistor Rf is the primary stability-determining element and should be chosen per the datasheet recommendation, typically in the range of 500 Ω to 1 kΩ. Using values much lower than recommended reduces loop gain margin and causes peaking; values much higher slow the bandwidth. Gain is then set independently by the gain resistor Rg, allowing bandwidth to remain essentially constant across gain settings from 1 to 10 or more.
Can the TSH330IDT be used in a transimpedance amplifier configuration for photodiode readout?
The TSH330IDT can be configured as a transimpedance amplifier for photodiode or other current-source inputs, where its current-feedback input stage provides inherently low inverting-node impedance. The feedback resistor directly sets the transimpedance gain in V/A. At a 1 kΩ feedback resistor, the amplifier provides 1 kV/A conversion with bandwidth determined primarily by the Rf × Cin time constant, making it appropriate for wideband photodetector readout in optical communication or industrial sensing systems.
How does TSH330IDT compare in terms of package and CMRR to a standard general-purpose op-amp like TL071?
Both TSH330IDT and TL071 are available in 8-pin SOIC packages, but the TSH330IDT is a wideband current-feedback amplifier with 50 dB minimum CMRR optimized for MHz-range signals, whereas the TL071 is a voltage-feedback JFET op-amp suited for audio and lower-frequency applications with higher CMRR typically above 70 dB. For video amplification, cable driving, or IF signal processing above 10 MHz, the TSH330IDT's current-feedback topology provides far superior bandwidth performance.
