STMicroelectronics TS9222IYDT

Overview

TS9222IYDT 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 single-supply operation, and drives capacitive loads up to 500 pF - enabling precision signal conditioning in automotive sensor interfaces and actuator drivers.

For engineers reviewing the TS9222IYDT datasheet, TS9222IYDT pinout, TS9222IYDT application, or TS9222IYDT equivalent, key selection criteria include rail-to-rail I/O swing, low 9 nV/√Hz input noise, high channel separation (120 dB), ±125°C operating range, and SO8 package compatibility with automotive PCB layouts.

Technical Context

The TS9222IYDT employs a fully differential input stage with rail-to-rail common-mode input range (VCC− −0.2 V to VCC+ +0.2 V) and rail-to-rail output swing within 50 mV of supply rails at 600 Ω load. Its unity-gain stable architecture achieves 60° phase margin with 100 pF capacitive load and remains stable up to 500 pF - critical for driving long traces or piezoelectric actuators without external compensation.

It integrates ESD protection (2 kV HBM), latch-up immunity, and operates across −40°C to +125°C ambient temperature. The device draws only 1.2 mA per channel typical supply current while delivering 80 mA short-circuit output current - supporting robust line drivers and servo amplifiers in harsh automotive environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual precision op-amp applications.

Compared with TS9222IYDT, TSV912IDT trades automotive qualification and 500 pF stability for higher bandwidth and lower cost, while LMV932M/NOPB sacrifices precision, output drive, and temperature range for ultra-low power and small footprint - making TS9222IYDT the sole choice for AEC-Q100-compliant, high-fidelity, high-drive dual op-amp roles.

FAQ

Is TS9222IYDT pin-compatible with TS9222ID?

Yes - TS9222IYDT and TS9222ID share identical SO8 pinout, electrical specifications, and thermal characteristics. The "Y" suffix denotes AEC-Q100 qualification and enhanced screening per AEC-Q001/Q002, while the base ID version is industrial-grade. Both use the same PCB footprint and schematic symbol.

Can TS9222IYDT drive a 1 nF capacitive load?

No - the datasheet guarantees stability only up to 500 pF. Driving 1 nF violates the specified capacitive load limit and risks oscillation due to phase margin degradation below 60°. For >500 pF loads, add a 10–100 Ω isolation resistor in series with the output or select a decompensated op-amp.

What is the maximum junction temperature during continuous 80 mA output into 600 Ω?

At 12 V supply and 600 Ω load, output current is ~20 mA (12 V/600 Ω); full 80 mA occurs only during short-circuit conditions. With Rthja = 125 °C/W (SO8), worst-case junction rise is ~10°C above ambient at 2.4 mA per channel quiescent draw - well below the 150°C absolute max, assuming proper PCB copper area.

Does TS9222IYDT support dual-supply operation?

Yes - it operates with split supplies (e.g., ±2.5 V to ±6 V) as well as single-ended supplies (2.7–12 V). The common-mode input range extends 0.2 V beyond both rails, and output swings rail-to-rail regardless of supply configuration - verified in Tables 3 and 4 of the datasheet across 3 V and 5 V single-supply and ±2.5 V/±6 V dual-supply test conditions.
