Product details
Overview
TS522ID from STMicroelectronics is a precision dual operational amplifier optimized for high-fidelity audio signal conditioning. It delivers 15 MHz gain bandwidth, 7 V/μs slew rate, ±14.3 V/–14.6 V output swing (RL = 10 kΩ), and ultra-low 4.5 nV/√Hz input voltage noise - enabling low-distortion amplification in line-level and preamplifier stages.
For engineers reviewing the TS522ID datasheet, TS522ID pinout, TS522ID application, or TS522ID equivalent, key selection criteria include input offset voltage (≤1.7 mV), common-mode rejection (80–100 dB), supply voltage range (±2.5 V to ±15 V), thermal resistance (125 °C/W for SO-8), and automotive-grade availability (TS522IYDT).
Technical Context
The TS522ID integrates two matched, internally compensated op-amps with rail-to-rail output stage capability and symmetrical source/sink current (29 mA sink / 20 mA source). Its architecture supports stable unity-gain operation (phase margin ≥30° at CL = 100 pF) and maintains ≤0.002% THD across 20 Hz–20 kHz at 3 Vrms output.
Designed for bipolar ±15 V operation, it features 175 kΩ input resistance, 12 pF input capacitance, and 37 Ω output impedance at 9 MHz - ensuring predictable loading behavior in multi-stage audio filters and active crossovers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 15 MHz - enables stable closed-loop gain up to ×100 at 150 kHz without peaking |
| Slew rate | 7 V/μs - preserves transient fidelity for 20 kHz full-scale audio signals (≥2.8 V/μs required) |
| Input voltage noise | 4.5 nV/√Hz at 1 kHz - minimizes audible hiss in microphone preamp and phono stage designs |
| Output voltage swing | ±14.3 V / –14.6 V (RL = 10 kΩ) - delivers >28 Vpp headroom into high-impedance loads |
| Input offset voltage | ≤1.7 mV max - reduces DC error in DC-coupled active filters and summing amplifiers |
| Common-mode rejection | 80–100 dB - suppresses power supply ripple and ground-bounce coupling in single-supply-derived rails |
| THD + noise | 0.002% at 20 Hz–20 kHz - meets Hi-Fi grade distortion requirements for consumer and pro-audio gear |
Pinout & Package
TS522ID is supplied in an SO-8 plastic micropackage (ECOPACK® compliant), with 1.27 mm pitch, 4.90 mm width, and 6.00 mm length. Thermal resistance is 125 °C/W (junction-to-ambient) and 40 °C/W (junction-to-case).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier 1) | Differential node for negative feedback configuration; accepts ±13 V common-mode range |
| 2 | Non-inverting input (Amplifier 1) | High-impedance reference node; 175 kΩ input resistance minimizes bias current error |
| 3 | Output (Amplifier 1) | Capable of sourcing 20 mA / sinking 29 mA into 600 Ω load |
| 4 | VCC− | Negative supply rail connection; must be decoupled within 1 cm of pin |
| 5 | VCC+ | Positive supply rail connection; shared by both amplifiers; requires local 100 nF ceramic bypass |
| 6 | Inverting input (Amplifier 2) | Independent differential input; matched to Pin 1 for stereo channel tracking |
| 7 | Non-inverting input (Amplifier 2) | Independent high-Z input; 12 pF capacitance affects RF immunity above 10 MHz |
| 8 | Output (Amplifier 2) | Electrically isolated output stage; 120 dB channel separation prevents crosstalk at audio frequencies |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset voltage drift | 2 μV/°C - ensures <10 μV total drift over –40°C to +125°C operating range |
| High slew rate with low distortion | 7 V/μs + 0.002% THD - enables clean 20 kHz square wave reproduction without overshoot |
| Large symmetrical output swing | ±14.3 V / –14.6 V - supports 28.6 Vpp dynamic range into 10 kΩ, critical for line-driver applications |
| Robust ESD protection | 2 kV HBM - withstands handling during PCB assembly without external clamping diodes |
| Wide supply voltage range | ±2.5 V to ±15 V - accommodates legacy ±12 V systems and modern ±15 V studio equipment rails |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher input bias current (800 nA vs. 750 nA typ), lower GBP (10 MHz), no guaranteed 125°C operation | Established in legacy audio gear; lacks AEC-Q100 qualification for automotive use | Select when cost sensitivity outweighs extended temperature or noise performance needs |
| OPA2134PA | FET-input (50 pA ib), lower noise (8 nV/√Hz), but only 8 MHz GBP and ±13.5 V swing (RL = 10 kΩ) | Better for ultra-high-Z sensor interfaces; insufficient slew rate for fast transient audio | Prefer for piezoelectric or photodiode preamps where input impedance >1 GΩ is mandatory |
Compared with NE5532DR and OPA2134PA, TS522ID uniquely balances low noise (4.5 nV/√Hz), high slew rate (7 V/μs), full automotive temperature range (–40°C to +125°C), and SO-8 ECOPACK® compliance - making it optimal for next-generation audio subsystems requiring reliability and fidelity.

FAQ
What is the maximum recommended supply voltage for continuous operation of TS522ID?
The absolute maximum supply voltage is ±18 V, but continuous operation must remain within the specified operating range of ±2.5 V to ±15 V. Exceeding ±15 V risks parametric shift and accelerated aging, even if within absolute limits. The device achieves optimal noise and distortion performance at ±15 V, with full output swing and thermal stability verified across –40°C to +125°C.
Does TS522ID require external compensation for unity-gain stable operation?
No external compensation is required. TS522ID is internally compensated for unity-gain stability, with measured phase margin ≥30° at 100 pF capacitive load and ≥55° with no load. This allows direct use in voltage-follower, inverting, and non-inverting configurations without risk of oscillation - confirmed by Figure 8 (gain/phase vs. frequency) in the official datasheet.
How does the TS522ID's channel separation performance impact stereo audio design?
With 120 dB channel separation from 20 Hz to 20 kHz, TS522ID prevents audible crosstalk between left/right channels in stereo line drivers and mixer buses. This specification is measured under real-world conditions (RL = 2 kΩ, full signal swing) and ensures >100 dB stereo imaging integrity - critical for mastering consoles and high-resolution streaming endpoints where inter-channel isolation directly impacts perceived soundstage width.
Can TS522ID be used in single-supply configurations?
TS522ID is specified for dual-supply operation (±2.5 V to ±15 V) and lacks rail-to-rail input capability - its common-mode input range is limited to ±13 V with ±15 V supplies. While it can operate with split virtual grounds (e.g., using resistive dividers and decoupling caps), ST does not characterize or guarantee performance in true single-supply mode. For dedicated single-supply audio op-amps, ST recommends the TSV912 or TS912 families.
