STMicroelectronics TS9222IYPT

Overview

TS9222IYPT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier with automotive qualification (AEC-Q100), 4 MHz gain-bandwidth product, 1.3 V/μs slew rate, and 500 µV max input offset voltage. It delivers 80 mA output current, supports 2.7–12 V supply, and drives capacitive loads up to 500 pF - enabling precision signal conditioning in automotive sensor interfaces and audio line drivers.

For engineers reviewing the TS9222IYPT datasheet, TS9222IYPT pinout, TS9222IYPT application, or TS9222IYPT equivalent, key selection criteria include rail-to-rail I/O swing at low supply (2.7 V), high output drive into 600 Ω loads, low 9 nV/√Hz input noise, and guaranteed operation from –40 °C to +125 °C for under-hood electronics.

Technical Context

The TS9222IYPT employs a proprietary bipolar input stage optimized for precision and stability, achieving 65–85 dB common-mode rejection and 70–90 dB supply voltage rejection across its full operating temperature range. Its unity-gain stable architecture maintains ≥60° phase margin with 100–500 pF capacitive loads - eliminating need for external compensation in driving cables or piezoelectric actuators.

Internal ESD protection (2 kV HBM) and latch-up immunity support robust deployment in automotive subsystems. The device operates without phase reversal under rail-to-rail input overvoltage conditions and sustains 80 mA short-circuit output current independent of supply voltage magnitude.

FAQ

Is TS9222IYPT pin-compatible with TS9222IDT?

Yes - both share identical TSSOP8 pinout and electrical specifications. The only difference is automotive qualification: TS9222IYPT undergoes AEC-Q100 stress testing (temperature cycling, HTOL, ESD), while TS9222IDT is industrial-grade. No PCB redesign is needed for migration.

Can TS9222IYPT drive a 1000 pF load?

No - datasheet guarantees stability only up to 500 pF. Driving larger capacitive loads risks oscillation due to reduced phase margin. For >500 pF, add a 10–100 Ω isolation resistor in series with the output, or select a decompensated op-amp like TS9224 with external compensation.

What is the maximum output current per channel under continuous short-circuit?

The absolute maximum output short-circuit current is 80 mA, measured at V_CC = 3 V and 5 V. This value is independent of supply voltage magnitude. Sustained short-circuit operation requires thermal derating per R_thJA = 120 °C/W (TSSOP8) to avoid exceeding 150 °C junction temperature.

Does TS9222IYPT support single-supply operation below 3 V?

Yes - it operates down to 2.7 V with full rail-to-rail input/output swing and specified performance (V_io ≤ 900 µV, GBP = 4 MHz). At 2.7 V, output swing is within 20 mV of each rail, and supply current remains 0.9–1.3 mA per channel across temperature.
