Product details
Overview
TL592B-8D from Texas Instruments is a monolithic two-stage differential video amplifier with differential inputs/outputs, adjustable gain up to 400 V/V (typ), 50 MHz bandwidth (–3 dB), and 3 µV broadband input noise voltage (typ) at 1 kHz–10 MHz. It operates from ±3 V to ±8 V dual supplies, supports 0°C to 70°C ambient, and drives capacitive loads via emitter-follower outputs - used in NRZ-encoded magnetic tape systems and high-speed thin-film memory interfaces.
For engineers reviewing the TL592B-8D datasheet, TL592B-8D pinout, TL592B-8D application, or TL592B-8D equivalent, this page delivers verified technical context, SOIC-8 package mapping, gain-adjust resistor interface details, differential output drive capability, and real-world video/pulse amplification use cases - all grounded in TI's SLFS001B revision April 2008 production data.
Technical Context
The TL592B-8D implements internal series-shunt feedback for wide bandwidth and low phase distortion, with current-source biasing enabling >50 dB CMRR (100 kHz) and >50 dB kSVR across 0°C–70°C. Its differential architecture accepts ±1 V common-mode input range and delivers ±1.4 V peak-to-peak output swing into 2 kΩ.
Gain is set externally via a single resistor (RAB) between pins 4 and 6; RAB = 0 Ω yields nominal 400× amplification, while RAB = 1 kΩ reduces gain to 250–600× depending on temperature. No external frequency compensation is required at any gain setting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Range | Adjustable 0–400 V/V via single RAB resistor; enables precise signal scaling without redesign. |
| Bandwidth | 50 MHz (–3 dB) at RAB = 0 Ω; supports NTSC/PAL video baseband and fast pulse amplification. |
| Input Noise Voltage | 3 µV rms (1 kHz–10 MHz); preserves SNR in low-level analog video paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6552MA/NOPB | Higher bandwidth (1.8 GHz), fixed-gain (10 V/V), requires external compensation; consumes 120 mA supply current. | Targeted at RF/IF signal chains, not legacy video or magnetic storage; unsuitable for low-power ±6 V systems. | Select only if >100 MHz bandwidth and DC-coupled RF gain are required; not drop-in compatible. |
| THS3201DGN | Single-ended input, differential output; 800 MHz bandwidth; 12 V supply minimum; no internal gain adjustment. | Designed for high-speed ADC/DAC interface buffering, not differential source amplification; lacks IN–/IN+ flexibility. | Choose for ultra-high-speed data converter interfaces where input common-mode range exceeds ±1 V. |
Compared with LMH6552MA/NOPB and THS3201DGN, the TL592B-8D offers uniquely adjustable gain, dual-supply operation down to ±3 V, and self-compensated stability - making it irreplaceable in cost-sensitive, legacy-compatible video and magnetic storage designs where precision gain tuning and low-noise analog integrity are critical.

FAQ
What is the maximum operating supply voltage for TL592B-8D?
The TL592B-8D supports a maximum positive supply voltage (VCC+) of +8 V and a maximum negative supply voltage (VCC–) of –8 V, as specified in the Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. For reliable long-term performance, TI recommends staying within the Recommended Operating Conditions of ±3 V to ±6 V, where key parameters like gain and bandwidth are fully characterized.
Does TL592B-8D require external frequency compensation components?
No, the TL592B-8D does not require external frequency compensation components at any gain setting. Its internal architecture provides inherent stability across the full 0–400 V/V gain range, as confirmed in the device description and Electrical Characteristics section of the SLFS001B datasheet. This eliminates layout sensitivity and reduces bill-of-materials count in video and pulse amplifier designs.
What is the function of pins 4 and 6 (GAIN ADJ A and GAIN ADJ B) on TL592B-8D?
Pins 4 (GAIN ADJ A) and 6 (GAIN ADJ B) form the terminals of an internal gain-setting network. Connecting an external resistor (RAB) between them adjusts differential voltage amplification from near 0 to 400 V/V. With RAB = 0 Ω (short), gain is ~400×; increasing RAB linearly reduces gain, enabling precise calibration without changing circuit topology.
Can TL592B-8D drive 75 Ω coaxial video cables directly?
Yes, the TL592B-8D can drive 75 Ω coaxial video cables directly using its emitter-follower output stage. While its nominal load specification is 2 kΩ, the device delivers ±1.4 V peak-to-peak swing and supports 10 mA output current. When paired with proper external termination (e.g., 75 Ω to ground at the receiver), it maintains signal integrity in composite video distribution applications without intermediate buffers.
Is TL592B-8D still in active production and supported by Texas Instruments?
Yes, TL592B-8D is listed as Active and in Production status per TI's official Package Option Addendum (11-Nov-2025). It is offered in SOIC (D) packaging with RoHS-compliant NiPdAu finish, MSL Level-1 rating, and 0°C to 70°C temperature grade. TI continues to provide full datasheet documentation (SLFS001B), application guidance, and manufacturing support for this part.
