Product details
Overview
TSZ182HYDT from STMicroelectronics is a dual, AEC-Q100 qualified zero-drift operational amplifier in SO8 package, designed for high-accuracy automotive sensor signal conditioning. It delivers 25 µV max offset voltage at 25 °C, 44 µV over –40 to +150 °C, rail-to-rail I/O, 3 MHz gain bandwidth, and operates from 2.2–5.5 V supply.
For engineers reviewing the TSZ182HYDT datasheet, TSZ182HYDT pinout, TSZ182HYDT application, or TSZ182HYDT equivalent, key selection criteria include ultra-low offset drift (0.15 µV/°C), extended temperature operation (–40 to +150 °C), EMI rejection ratio up to 85 dB at 2.4 GHz, and SO8 pin compatibility for current-sense amplifier front-ends in battery management and motor control systems.
Technical Context
The TSZ182HYDT implements auto-zeroing architecture to achieve near-zero input offset drift versus temperature and time. Its dual-channel design supports independent high-precision signal paths with matched DC performance across channels - confirmed by ≤0.4 µVpp 0.1–10 Hz noise and 135 dB channel separation at 100 Hz.
It features rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and output swing within 13–70 mV of rails, enabling full dynamic range utilization in low-voltage (2.2 V) automotive systems. The 3 MHz GBP and 4.7 V/µs slew rate support fast settling (600 ns to 0.1%) for high-bandwidth current sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 25 µV max at 25 °C; enables <1 LSB error in 16-bit ADC interfaces without calibration. |
| Offset Drift | 0.15 µV/°C over –40 to +150 °C; ensures stable gain accuracy in under-hood environments. |
| Supply Range | 2.2–5.5 V; supports direct connection to 3.3 V or 5 V automotive microcontroller domains. |
| Gain Bandwidth | 3 MHz at 5 V; allows closed-loop bandwidth >1 MHz for fast current-loop feedback. |
| EMI Rejection | 85 dB at 2.4 GHz; mitigates RF interference from infotainment or cellular modules in vehicle ECUs. |
| Output Drive | 29 mA sink / 25 mA source at 5 V; drives 10 kΩ loads with <70 mV rail margin for robust rail-to-rail output. |
| Input Bias Current | 200 pA max at 25 °C; minimizes voltage error in high-impedance sensor bridges (e.g., strain gauges). |
Pinout & Package
TSZ182HYDT is housed in an SO8 (Small Outline 8-pin) package per JEDEC MS-012, with 1.27 mm pitch, 4.9 mm × 6.0 mm body, and 1.75 mm height. Thermal resistance θJA is 125 °C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | Differential input node for first op-amp; accepts rail-to-rail common-mode signals. |
| 2 | Non-inverting Input (Channel A) | Reference input for Channel A; matched offset and CMRR with Pin 1. |
| 3 | Output (Channel A) | Full rail-to-rail output capable of sourcing/sinking ≥25 mA at 5 V. |
| 4 | VCC− (Ground) | Power return for both channels; requires low-impedance PCB ground plane. |
| 5 | Output (Channel B) | Independent output for second op-amp; electrically isolated from Channel A. |
| 6 | Non-inverting Input (Channel B) | Reference input for Channel B; matched performance to Pin 2 across temperature. |
| 7 | Inverting Input (Channel B) | Differential input node for second op-amp; identical specs to Pin 1. |
| 8 | VCC+ (Supply) | Positive supply rail (2.2–5.5 V); decoupling capacitor required within 1 cm. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-accuracy automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Single-channel, 1 µV typical offset, 2.7–5.5 V supply, 2.5 MHz GBP, SO8. | Lacks dual-channel integration; requires two devices for same functionality as TSZ182HYDT. | Choose when single-channel operation suffices and lower typical offset is prioritized over channel matching. |
| MAX44268ASA+ | Dual-channel, 3 µV typical offset, 2.7–5.5 V, 10 MHz GBP, SO8, no AEC-Q100 qualification. | Higher bandwidth but unqualified for automotive; lacks EMI rejection data above 1 GHz. | Prefer for industrial test equipment where speed matters more than automotive compliance or RF immunity. |
Compared with AD8628ARZ and MAX44268ASA+, TSZ182HYDT uniquely combines AEC-Q100 Grade 0 qualification, dual-channel zero-drift performance, and validated 2.4 GHz EMI rejection - making it the only drop-in solution for ASIL-B/C current-sense front-ends requiring guaranteed drift stability across extreme temperature cycling.

FAQ
What is the maximum operating junction temperature for TSZ182HYDT?
The absolute maximum junction temperature is 160 °C, and the device is fully specified for continuous operation from –40 to +150 °C ambient. Thermal resistance θJA is 125 °C/W in SO8, so at 1.2 mA supply current and 5 V supply, power dissipation remains below 6 mW - well within safe limits even in sealed enclosures.
Does TSZ182HYDT support single-supply operation with rail-to-rail inputs below ground?
No. The input common-mode range extends from VCC− −0.1 V to VCC+ +0.1 V, meaning it does not accept inputs below the negative rail (e.g., –0.1 V relative to ground). For true bipolar input capability, external level-shifting circuitry is required.
How is EMI rejection measured, and which pin is sensitive?
EMI rejection ratio (EMIRR) is measured per DS13229 Rev 2, with 100 mVp RF injection on the inverting input (Pin 1 or Pin 7), while monitoring output deviation. Values reach 85 dB at 2.4 GHz, confirming robustness against cellular band interference in telematics-integrated ECUs.
Can TSZ182HYDT drive a 100 pF capacitive load without oscillation?
Yes. The datasheet confirms stable operation with 100 pF load and 10 kΩ resistive load (Table 3–5), achieving ≥56° phase margin. Figure 30 shows minimal overshoot (<5%) up to 200 pF, supporting direct interface to SAR ADC sample capacitors without external isolation resistors.
