Product details

Overview

TSX922IYDT from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for high-speed precision signal conditioning in automotive and industrial systems. It delivers 10 MHz gain bandwidth, 17.2 V/µs negative slew rate, and 0.0003 % THD+N at 1 kHz with 4 V–16 V supply, operating across –40 °C to 125 °C. Its low 10 pA input bias current and 4 kV HBM ESD tolerance support robust sensor interface and active filtering applications.

For engineers reviewing the TSX922IYDT datasheet, TSX922IYDT pinout, TSX922IYDT application, or TSX922IYDT equivalent, key selection criteria include rail-to-rail operation under wide supply (4–16 V), automotive-grade temperature range (–40 °C to 125 °C), low-noise performance (16.5 nV/√Hz at 10 kHz), and dual-channel MiniSO8 packaging for space-constrained analog front-ends.

Technical Context

The TSX922IYDT employs a CMOS input stage enabling ultra-low input bias current (10 pA typ) and high input resistance (1 TΩ), critical for high-impedance sensor buffering. Its unity-gain-stable architecture supports stable closed-loop operation without external compensation across its full 10 MHz bandwidth.

Designed for demanding analog signal chains, it maintains rail-to-rail output swing within 50 mV of supply rails at 10 kΩ load and achieves 85 dB CMRR over extended common-mode range (–0.1 V to 16.1 V at V_CC = 16 V), ensuring accuracy in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain Bandwidth Product	10 MHz at 16 V - enables stable amplification up to 10 MHz with gain ≥1, suitable for active filters and broadband signal conditioning.
Slew Rate (Negative)	17.2 V/µs at 16 V - supports fast transient response for pulse amplification and high-fidelity audio pre-amplification.
Input Bias Current	10 pA typ - minimizes voltage error in high-impedance photodiode or pH sensor interfaces.
THD+N	0.0003 % at 1 kHz, 4 V_RMS out - ensures high-fidelity signal integrity in precision measurement and communications circuits.
ESD Tolerance	4 kV HBM - provides robust handling during PCB assembly and field operation in automotive ECUs.
Operating Temperature	–40 °C to 125 °C - qualified for under-hood automotive and industrial control applications without derating.
Supply Voltage Range	4 V to 16 V - compatible with 5 V, 12 V, and 15 V industrial power rails without external regulators.

Pinout & Package

The TSX922IYDT is housed in an 8-pin MiniSO package (3.0 mm × 4.9 mm, 1.75 mm height), optimized for thermal performance (R_thJA = 190 °C/W) and board-level reliability in high-vibration environments.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT1)	Channel 1 output	Delivers rail-to-rail output swing; capable of sourcing/sinking 50 mA at 16 V for driving moderate loads directly.
2 (IN1–)	Channel 1 inverting input	High-impedance CMOS node; accepts differential signals up to ±V_CC mV with 1 TΩ input resistance.
3 (IN1+)	Channel 1 non-inverting input	Supports common-mode input range from (V_CC–) – 0.1 V to (V_CC+) + 0.1 V - enables single-supply sensor interfacing.
4 (V_CC–)	Negative supply rail	Ground reference for dual-supply use or system ground in single-supply configurations.
5 (V_CC+)	Positive supply rail	Accepts 4–16 V; internal protection limits absolute max to 18 V per absolute ratings table.
6 (IN2+)	Channel 2 non-inverting input	Independent high-Z input; identical specs to IN1+, enabling matched dual-channel instrumentation.
7 (IN2–)	Channel 2 inverting input	Paired with IN2+ for second differential path; crosstalk < –120 dB at 1 MHz per Figure 35.
8 (OUT2)	Channel 2 output	Electrically isolated from OUT1; supports independent gain stages or I/V conversion for dual ADC channels.

Key Features

Feature	Design Value
Rail-to-rail I/O	Output swings within 50 mV of rails at 10 kΩ load; input common-mode extends 0.1 V beyond supplies - eliminates level-shifting in 3.3 V/5 V/12 V systems.
Automotive qualification	AEC-Q100 Grade 1 compliant - validated for continuous operation at 125 °C ambient in engine control and ADAS subsystems.
Low input noise	16.5 nV/√Hz at 10 kHz and 8.58 µV_PP (0.1–10 Hz) - preserves SNR in precision weigh scales and medical front-ends.
High PSRR	85 dB at DC, >60 dB up to 100 kHz - rejects ripple from switching power supplies in motor drive feedback loops.
Unity-gain stability	No external compensation required - simplifies layout for gain-of-1 buffers and active filters without phase-margin risk.

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
TSV912IDT	Lower supply range (2.7–5.5 V), 8 MHz GBW, 1.1 mA ICC - optimized for low-voltage portable gear.	Not rated for >5.5 V or automotive temp range; unsuitable for 12 V industrial sensors.	Select only for battery-powered handheld test tools requiring sub-2 mA quiescent current.
LMV358IDR	Wider supply (2.7–5.5 V), 1 MHz GBW, 70 µA ICC - general-purpose CMOS dual op-amp with lower speed.	Lacks rail-to-rail output swing and automotive qualification; limited to commercial-temp consumer electronics.	Choose for cost-sensitive, non-critical applications like LED dimmer feedback where 10 MHz bandwidth is unnecessary.

Compared with TSV912IDT and LMV358IDR, the TSX922IYDT uniquely combines 10 MHz bandwidth, 4–16 V operation, and AEC-Q100 Grade 1 qualification - making it the only viable option for dual-channel high-speed analog signal conditioning in automotive and industrial 12 V systems.

FAQ

What is the maximum capacitive load the TSX922IYDT can drive without instability?

The TSX922IYDT remains stable with up to 120 pF capacitive load when configured with 10 kΩ feedback and gain ≥1, as verified in Figure 21 of DS9502 Rev 5. For loads >47 pF, adding a 2–3 pF feedback capacitor (Figure 28) restores phase margin above 55°. Driving >200 pF requires isolation resistor or dedicated buffer stage.

Does the TSX922IYDT support shutdown mode?

No - the TSX922IYDT lacks a shutdown pin. Shutdown functionality is only available on the TSX920 (SOT23-6) and TSX923 (MiniSO10) variants per datasheet Section 3. The TSX922IYDT is designed for always-on precision applications where quiescent current (2.8 mA per amplifier at 16 V) is acceptable.

How does input offset voltage drift behave over temperature and time?

For TSX922IYDT, ∆V_IO/∆T is 2–15 µV/°C (typ/max), and long-term drift is 2.26 nV/√month at 125 °C per Table 5. This translates to ~0.8 µV drift after 1000 hours at 125 °C - critical for uncalibrated 16-bit systems where offset must stay below 1 LSB (15.3 µV).

Can the TSX922IYDT be used as a comparator?

It is not recommended. While functional, datasheet Note 2 warns of permanent input offset drift (several mV) when used as a comparator with high differential voltage at V_CC ≈ 16 V and low temperatures. Dedicated comparators (e.g., TS882) offer faster response, built-in hysteresis, and guaranteed open-collector outputs.
