Product details
Overview
TS9224IPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for precision signal conditioning in automotive and industrial systems. It delivers 4 MHz gain-bandwidth, 1.3 V/μs slew rate, 500 µV max input offset voltage, and drives capacitive loads up to 500 pF - enabling stable operation in headphone amplifiers and servo control loops.
For engineers reviewing the TS9224IPT datasheet, TS9224IPT pinout, TS9224IPT application, or TS9224IPT equivalent, this device supports high-accuracy analog front-ends requiring low noise (9 nV/√Hz), high output current (80 mA), and wide supply range (2.7–12 V) across temperature (−40°C to +125°C).
Technical Context
The TS9224IPT integrates four independent op-amps in a single TSSOP14 package with fully rail-to-rail input and output stages, enabling full dynamic range utilization in single-supply systems. Its internal architecture ensures stability with capacitive loads up to 500 pF without external compensation.
It features 85 dB typical common-mode rejection ratio (CMRR) and 90 dB typical supply voltage rejection ratio (SVRR) at 5 V supply, supporting precision DC-coupled amplification in noisy environments. Phase margin remains ≥60° at unity gain with 100 pF load, confirming robust small-signal stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower GBW (6.4 MHz), higher quiescent current (650 µA/channel), no automotive qualification. | Not AEC-Q100 qualified; limited to commercial temperature range (−40°C to +85°C). | Preferred where higher speed is critical and automotive qualification is unnecessary. |
| LMV324IPWR | Lower output current (40 mA), higher input offset (3 mV max), no 500 pF capacitive load guarantee. | Not suitable for direct capacitive load driving or high-current actuator interfaces. | Select when cost sensitivity outweighs precision and drive strength requirements. |
Compared with TLV2464IDR and LMV324IPWR, the TS9224IPT uniquely combines AEC-Q100 qualification, 80 mA output drive, and guaranteed 500 pF capacitive load stability - making it the only choice for automotive-grade quad op-amp applications demanding both precision and robustness.

FAQ
Is the TS9224IPT pin-compatible with the TS9224ID SO14 variant?
Yes - the TS9224IPT (TSSOP14) and TS9224ID (SO14) share identical pin numbering and electrical functionality. The TSSOP14 offers reduced PCB area and improved thermal resistance (100 °C/W vs. 66 °C/W for SO14), but requires finer-pitch reflow profiling due to 0.65 mm lead pitch.
Can the TS9224IPT drive a 1000 pF load?
No - the datasheet guarantees stability only up to 500 pF. Driving 1000 pF loads may cause peaking or oscillation. For larger capacitive loads, add a 10–100 Ω isolation resistor between Outx and the load, or use an external unity-gain buffer with higher CL tolerance.
What is the maximum safe continuous output current per channel?
The absolute maximum output current is 80 mA per channel, but sustained operation above 50 mA requires careful thermal design. At 80 mA into 600 Ω with VCC = 12 V, junction temperature rise exceeds 80°C - derate output current by 10% per 10°C ambient increase above 85°C.
Does the TS9224IPT include internal ESD protection on all pins?
Yes - all input and output pins feature integrated 3 kV HBM ESD protection per JEDEC JS-001, plus 1 kV CDM protection. This eliminates need for external TVS diodes in most automotive and industrial I/O protection schemes, provided layout follows ST's recommended grounding and trace routing guidelines.
