Texas Instruments THS4513RGTT

Overview

THS4513RGTT from Texas Instruments is a wideband, fully-differential amplifier optimized for 5-V data acquisition systems. It delivers 2.2 nV/√Hz input voltage noise, –75 dBc HD2 and –86 dBc HD3 at 70 MHz (2-VPP output), 5100 V/μs slew rate, and 2.9 ns 1% settling time - enabling high-fidelity signal conditioning ahead of high-speed ADCs in test equipment and medical imaging front-ends.

For engineers reviewing the THS4513RGTT datasheet, THS4513RGTT pinout, THS4513RGTT application, or THS4513RGTT equivalent, key selection criteria include its 0-dB minimum gain capability, output common-mode control with ±5-mV offset, 1600-MHz small-signal bandwidth, and QFN-16 thermal-pad package requiring proper PCB thermal management.

Technical Context

The THS4513RGTT employs a fully-differential architecture with centered input common-mode range (1.1 V to 3.9 V on 5-V supply) and integrated output common-mode voltage control circuitry. Its differential outputs drive 200-Ω loads with 4.8–5.6 V swing while maintaining balance error < –52 dB at 1 MHz.

It supports single-ended input with differential output configuration, features power-down mode (0.65 mA quiescent current), and maintains stable performance across –40°C to +85°C. The CM input accepts –1.5 V to +1.5 V with 1 V/V gain and 250-MHz bandwidth when operating at 5-V supply.

Key Specifications

Pinout & Package

The THS4513RGTT is housed in a 4-mm × 4-mm, 16-pin quad flat no-lead (QFN) package with exposed thermal pad (RGT). The pad must be soldered to a PCB thermal plane for reliable operation at full power dissipation (2.3 W at TA ≤ +25°C).

FAQ

What is the minimum stable gain for THS4513RGTT?

The THS4513RGTT is specified for stable operation at a minimum gain of 0 dB (unity gain). This is explicitly confirmed in the datasheet's FEATURES section and electrical characteristics tables, enabling direct use as a unity-gain differential buffer without external gain-setting resistors.

Does THS4513RGTT support DC-coupled output to an ADC?

Yes, THS4513RGTT supports true DC-coupled output via its dedicated CM pin, which controls output common-mode voltage with ±5-mV offset accuracy when set within 0.5 V of midsupply. This eliminates the need for AC-coupling capacitors when interfacing with DC-coupled ADCs like the ADS54J60 or similar.

What is the thermal pad requirement for THS4513RGTT?

The THS4513RGTT's exposed thermal pad (pin 17, not numbered) must be soldered to a PCB copper pour tied to ground for effective heat dissipation. Per TI's SLMA002/SLMA004 guidelines, failure to do so risks exceeding the 150°C maximum junction temperature, especially at full 37.7-mA quiescent current and 2.3-W power dissipation.

Can THS4513RGTT operate from a single 5-V supply?

Yes, THS4513RGTT operates from a single 5-V supply configured as ±2.5 V (VS+ = 2.5 V, VS− = –2.5 V), with input common-mode range of 1.1 V to 3.9 V and output swing of 4.8–5.6 V differential. Its internal circuitry defaults CM to midsupply, and the CM pin allows overdrive for precise level setting.

What is the power-down behavior of THS4513RGTT?

When the PD pin is pulled low (≤0.7 V referenced to VS−), THS4513RGTT enters power-down mode with 0.65-mA typical quiescent current, 10-μs turn-off delay, and 55-ns turn-on delay. Input bias current drops to 100 μA, and outputs enter high-impedance state - ideal for dynamic power management in burst-mode instruments.
