Product details
Overview
TS922AIYPT from STMicroelectronics is a rail-to-rail input/output dual BiCMOS operational amplifier optimized for 3 V and 5 V battery-powered audio systems, featuring 4 MHz gain-bandwidth product, 1 V/μs slew rate, 9 nV/√Hz input voltage noise, 80 mA output drive into 32 Ω, and 900 μV max input offset voltage (TS922A grade) across –40 °C to +125 °C.
For engineers reviewing the TS922AIYPT datasheet, TS922AIYPT pinout, TS922AIYPT application, or TS922AIYPT equivalent, this device is selected for low-noise portable speaker drivers, line-level instrumentation interfaces, and multimedia system output stages where rail-to-rail swing, high capacitive load stability (up to 500 pF), and ESD-hardened (2 kV HBM) operation are required.
Technical Context
The TS922AIYPT integrates two matched BiCMOS op-amps in a single TSSOP8 package, with independent rail-to-rail input common-mode range (VCC– – 0.2 V to VCC+ + 0.2 V) and rail-to-rail output swing within 180 mV of supply rails at 32 Ω load. Its 4 MHz GBP and 1 V/μs slew rate support unity-gain-stable operation with ≥68° phase margin into 600 Ω + 100 pF loads.
Designed for low-voltage audio signal conditioning, it delivers <0.005% THD+N at 1 kHz with 2 Vpp output into 600 Ω, maintains 120 dB channel separation, and achieves 80 dB CMRR and SVRR over full temperature range - enabling high-fidelity dual-channel amplification without external level-shifting or biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports single-supply operation from Li-ion (3.3 V) up to industrial 12 V rails without level translation. |
| Gain-Bandwidth Product | 4 MHz - enables stable unity-gain buffer or 2× inverting amplifier configurations up to ~2 MHz signal bandwidth. |
| Slew Rate | 1 V/μs - ensures ≤1.2 μs settling time for 1 V step, sufficient for CD-quality (20 kHz) audio full-scale transients. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - contributes <1.8 μV RMS integrated noise in 20 Hz–20 kHz band, critical for microphone preamp or DAC output buffering. |
| Output Drive Capability | 80 mA short-circuit current - directly drives 32 Ω headphones or piezo actuators without external buffers or current boosters. |
| Input Offset Voltage (max) | 900 μV at 25 °C (TS922A grade) - limits DC error to <1.8 mV in 2× gain stage, avoiding audible pop during power-up in portable speakers. |
| ESD Protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 for handheld device front-end protection without external TVS diodes. |
Pinout & Package
TSSOP8 package: 3.0 mm × 6.4 mm body, 0.65 mm pitch, 1.05 mm max height, lead-free and RoHS-compliant per ECOPACK® specifications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts differential signal reference; rail-to-rail common-mode range allows direct connection to DAC output or sensor bridge. |
| 2 | Non-inverting input (Amplifier A) | High-impedance node (100 nA max bias current); used for unity-gain follower or precision reference buffering. |
| 3 | Output (Amplifier A) | Delivers rail-to-rail swing into 32 Ω; stable with 500 pF capacitive load - suitable for driving coaxial cables or LCD backlight dimming circuits. |
| 4 | VCC– (Ground) | Power return path; must be low-inductance connection to minimize ground bounce in dual-channel audio paths. |
| 5 | VCC+ | Positive supply rail; decoupling capacitor (100 nF ceramic) required within 5 mm for stable 4 MHz operation. |
| 6 | Inverting input (Amplifier B) | Matched to Pin 1; enables stereo line driver or differential receiver configuration with <1.5 mV inter-channel offset. |
| 7 | Non-inverting input (Amplifier B) | Independent high-Z input; supports dual-sensor signal conditioning with common-mode rejection >56 dB over temperature. |
| 8 | Output (Amplifier B) | Electrically isolated from Pin 3; enables true dual-channel operation without crosstalk-induced distortion (120 dB separation). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems - output swings within 180 mV of rails at 32 Ω, preserving 94% of available voltage headroom. |
| Low-noise architecture | 9 nV/√Hz input voltage noise at 1 kHz ensures <0.005% THD+N in 600 Ω loads, meeting Class D amplifier feedback loop requirements. |
| High-output-current design | 80 mA drive capability eliminates need for discrete emitter-follower stages when interfacing with 32 Ω speakers or analog switches. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IDR | Lower GBP (2 MHz), higher input offset (2 mV), no automotive qualification | Limited to commercial-temp consumer audio; insufficient for industrial actuator control requiring 125 °C operation | Select only for cost-sensitive non-automotive designs where 2 MHz bandwidth suffices |
| OPA2333AIDR | Zero-drift architecture (0.02 μV/°C drift), lower noise (5.5 nV/√Hz), but 350 μA supply current vs. 3 mA | Better DC precision for sensor front-ends, but lower output drive (25 mA) limits 32 Ω headphone use | Prefer for ultra-low-drift instrumentation; avoid where 80 mA load drive is mandatory |
Compared with TLV2772IDR and OPA2333AIDR, the TS922AIYPT uniquely balances high output current, automotive temperature range, and audio-grade noise performance - making it irreplaceable in portable speaker drivers requiring both robustness and fidelity.

FAQ
What is the maximum capacitive load the TS922AIYPT can drive while remaining stable?
The TS922AIYPT is specified stable with capacitive loads up to 500 pF when configured as a unity-gain buffer, as verified by phase margin ≥68° and gain margin ≥12 dB in the datasheet (DS1117 Rev 13, Figure 5). This allows direct connection to long PCB traces, LCD panel drivers, or coaxial cables without isolation resistors - critical for minimizing signal degradation in portable audio routing.
Does the TS922AIYPT require external compensation for unity-gain operation?
No external compensation is required. The TS922AIYPT is internally compensated for unity-gain stability across its full operating range (2.7 V to 12 V supply, –40 °C to +125 °C), with guaranteed phase margin ≥68° into 600 Ω + 100 pF loads (DS1117 Rev 13, Table 3). This eliminates design risk in battery-powered audio buffers where layout space and component count are constrained.
How does the TS922AIYPT's 80 mA output current translate to real-world load capability?
The 80 mA short-circuit current rating enables reliable 32 Ω headphone driving at 2.63 VOL and 2.63 VOH (at 3 V supply), delivering 82 mW per channel - sufficient for loud listening levels in portable speakers. It also supports 600 Ω line drivers with <100 mV output swing error, ensuring compatibility with professional audio equipment inputs.
Is the TS922AIYPT pin-compatible with other dual op-amps in TSSOP8 packages?
The TS922AIYPT uses standard TSSOP8 pinout (SOIC-8 compatible footprint), matching industry conventions for dual op-amps: Pins 1–3 (A amp), Pin 4 (GND), Pins 5–8 (B amp + VCC+). However, electrical characteristics - especially 80 mA drive, 4 MHz GBP, and rail-to-rail output - differ significantly from generic dual op-amps like LM358 or MCP6022, so functional replacement requires validation of load, speed, and noise requirements.
