Product details
Overview
TS9224IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-precision, low-noise automotive applications. 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 while operating from 2.7 V to 12 V supply. It is AEC-Q100 qualified and used in servo amplifiers and line drivers.
For engineers reviewing the TS9224IYPT datasheet, TS9224IYPT pinout, TS9224IYPT application, or TS9224IYPT equivalent, key selection criteria include rail-to-rail I/O swing, 80 mA output current capability, ±125 °C operating temperature range, THD of 0.005% at 1 kHz, and SO14/TSSOP14 package compatibility with automotive PCB layouts.
Technical Context
The TS9224IYPT integrates four independent precision op-amps with matched internal architecture enabling consistent DC accuracy (±900 µV max Vio over temperature) and dynamic performance (4 MHz GBP, 63° phase margin at unity gain with 100 pF load). Its rail-to-rail input stage uses complementary differential pairs, and the output stage supports class-AB drive into 600 Ω loads with <120 mV VOL.
Designed for stability with capacitive loads, it maintains ≥60° phase margin up to 500 pF without external compensation. The device features 9 nV/√Hz input noise at 1 kHz, 120 dB channel separation, and 85 dB CMRR across its full common-mode range (VCC−–0.2 V to VCC+ +0.2 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Lower GBP (1 MHz), higher Vio (3 mV max), no 500 pF load stability guarantee. | Cost-optimized entry-level automotive op-amp; not suitable for high-fidelity audio or precision sensor front-ends. | Select when budget constraints outweigh precision and stability requirements in non-critical signal paths. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower noise (5.5 nV/√Hz), but only 360 kHz GBP and 25 mA output. | Better for ultra-low-drift DC applications (e.g., weigh scales); insufficient bandwidth/current for audio or actuator drive. | Choose for µV-level DC stability where speed and drive strength are secondary to long-term offset drift. |
Compared with LMV324QDRQ1 and OPA2333PWR, TS9224IYPT uniquely balances 4 MHz bandwidth, 80 mA drive, 500 pF stability, and AEC-Q100 qualification - making it optimal for automotive audio, servo control, and multi-channel sensor hubs where both precision and power delivery matter.

FAQ
What is the maximum capacitive load the TS9224IYPT can drive without oscillation?
The TS9224IYPT is characterized and guaranteed stable with capacitive loads up to 500 pF across its full operating temperature range (−40 °C to +125 °C) and supply voltage range (2.7 V to 12 V), as verified in Figure 4 of the official datasheet. No external series resistor or compensation network is required for loads ≤500 pF.
Does TS9224IYPT support dual-supply operation?
Yes - TS9224IYPT operates with split supplies from ±1.35 V to ±6 V (total supply range 2.7 V to 12 V). Its rail-to-rail input and output stages function correctly with VCC+ and VCC− referenced to system ground or symmetric rails, enabling use in traditional dual-supply instrumentation circuits.
Is the TS9224IYPT pin-compatible with standard SO14 quad op-amps like TL074 or LM324?
No - TS9224IYPT uses the TSSOP14 pinout (not SO14), and its pin mapping differs from legacy quad op-amps. For example, VCC− is on Pin 4 (not Pin 4 of SO14 LM324, which is In1−), and VCC+ is on Pin 8 (not Pin 14). Direct replacement requires PCB redesign and layout verification per Figure 15 in the datasheet.
What is the typical input bias current of TS9224IYPT at 25°C?
The typical input bias current is 55 nA at 25°C, with a guaranteed maximum of 90 nA over the full operating temperature range (−40 °C to +125 °C), as specified in Table 3 and Table 4 of the datasheet. This enables high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance) without significant DC error.
