Product details
Overview
TL026PS-MAND from Texas Instruments is a monolithic two-stage differential high-frequency amplifier with AGC, designed for IF/RF signal conditioning in analog receiver chains. It delivers 38 dB typical peak gain, 50 MHz −3 dB bandwidth, and 50 dB typical AGC range while maintaining low harmonic distortion and stable gain across temperature (0°C to 70°C). Its emitter-follower outputs drive capacitive loads in TV, radio, and magnetic storage AGC circuits.
For engineers reviewing the TL026PS-MAND datasheet, TL026PS-MAND pinout, TL026PS-MAND application, or TL026PS-MAND equivalent, key selection criteria include differential voltage amplification (55–115 V/V), AGC-controlled gain variation (±180 mV around Vref), common-mode output stability (±300 mV shift), input resistance (8–30 kΩ), and supply current (22–30 mA) under ±6 V operation.
Technical Context
The TL026PS-MAND implements a current-source biased two-stage architecture with internal feedback for wide bandwidth and low phase distortion. Its AGC control operates differentially via the AGC pin referenced to the internally generated 1.3–1.5 V REF OUT voltage, enabling precise electronic attenuation without external compensation components.
All stages use current-source biasing to achieve high common-mode rejection (50–86 dB) and supply-voltage rejection (50–70 dB). The device supports differential input and output configurations, with emitter-follower outputs providing low 20 Ω output impedance and 3–4 VPP swing into 2 kΩ loads.
Key Specifications

Applications
| Television IF Amplification | FM Radio Receiver AGC |
|---|---|
Use Scenario: Amplifying intermediate frequency signals (41–47 MHz) after mixer stage in analog TV tuners. IC Role / Device Role / Timing Role: Differential high-frequency amplifier with automatic gain control to maintain constant video signal amplitude despite varying antenna input strength. Use Value: 50 MHz bandwidth preserves chroma/luma separation; 50 dB AGC range accommodates >60 dB RF signal variation without clipping. | Use Scenario: Stabilizing audio baseband output in FM radio receivers following quadrature detection. IC Role / Device Role / Timing Role: Differential post-detection amplifier whose gain adjusts dynamically to compensate for multipath fading and signal dropouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential high-frequency amplifier with AGC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE592N | Same pinout and functional architecture; lower −3 dB bandwidth (35 MHz vs. 50 MHz); higher supply current (35 mA vs. 22–30 mA) | Less suitable for VHF IF stages above 40 MHz; better thermal stability at elevated ambient temperatures | Select NE592N when board space allows TO-99 metal can package and thermal management prioritizes long-term drift over bandwidth |
| uA733CP | Pin-compatible PDIP variant; identical electrical specs but rated only to 30 MHz bandwidth; no REF OUT pin - requires external reference for AGC biasing | Applicable where cost-sensitive through-hole assembly is required and system bandwidth ≤30 MHz | Choose uA733CP for legacy repair or low-frequency AGC designs where REF OUT functionality is not needed |
Compared with NE592N and uA733CP, TL026PS-MAND offers superior 50 MHz bandwidth and integrated 1.4 V reference, enabling compact, high-fidelity AGC loops in modern analog receiver upgrades without external bias networks or bandwidth trade-offs.

FAQ
What is the operating temperature range for TL026PS-MAND?
The TL026PS-MAND is characterized for operation from 0°C to 70°C. This commercial-grade temperature range aligns with its intended use in consumer electronics such as TV tuners and FM radios. Electrical parameters-including gain, bandwidth, and AGC range-are guaranteed across this full range when powered from ±6 V supplies, as specified in the recommended operating conditions table of the SLFS007A datasheet. The device's current-source biasing contributes to stable performance within this interval.
Does TL026PS-MAND require external compensation components?
No, TL026PS-MAND does not require external compensation components. Its internal feedback architecture is fully compensated for stable operation across its entire 0–50 MHz bandwidth under unity-gain and closed-loop conditions. This eliminates the need for external capacitors or resistors on the AGC, input, or output pins-reducing bill-of-materials count and PCB area. The design achieves this while maintaining low phase distortion and excellent gain stability, as confirmed in the "description" section and Figure 2 test circuit of the SLFS007A datasheet.
How is the AGC function implemented in TL026PS-MAND?
The AGC function in TL026PS-MAND is implemented via a differential control voltage applied between the AGC pin (Pin 3) and the internal 1.3–1.5 V REF OUT voltage (Pin 7). A change of ±180 mV relative to Vref reduces gain from maximum to minimum-providing a 50 dB typical control range. This differential scheme ensures thermal tracking and minimizes drift, as both the AGC input and reference originate from the same die. The SLFS007A datasheet confirms this behavior in Figure 5 and the "gain characteristics" application note.
What is the purpose of the REF OUT pin on TL026PS-MAND?
REF OUT (Pin 7) provides a stable 1.3–1.5 V DC reference voltage derived from an internal bandgap circuit. It serves as the bias reference for the AGC control loop, enabling externally generated VAGC to be centered around this value-ensuring accurate, temperature-stable gain attenuation. Unlike alternatives such as uA733CP, TL026PS-MAND integrates this reference, eliminating the need for external voltage dividers or precision references. Its specification is verified in the "electrical characteristics" tables under Vref parameter.
Can TL026PS-MAND drive coaxial cables or 50 Ω transmission lines directly?
TL026PS-MAND is not optimized for direct 50 Ω source termination. Its output resistance is 20 Ω, and maximum output swing is 4 VPP into 2 kΩ-indicating design intent for medium-impedance loads (≥1 kΩ). Driving 50 Ω lines would reduce swing to <1 VPP and risk instability or distortion. For 50 Ω interfaces, a discrete emitter-follower buffer or dedicated line driver (e.g., THS3091) should follow TL026PS-MAND. The datasheet's Figure 1 test circuit explicitly uses 50 Ω terminations only for measurement, not operation.
