Product details
Overview
TSB182IYST from STMicroelectronics is a dual-channel, rail-to-rail output, high-precision chopper-stabilized operational amplifier with 20 µV max input offset voltage at 25 °C, 3 MHz gain bandwidth product, and operation across 4–36 V supply. It features EMI hardening, 4 kV HBM ESD tolerance, and AEC-Q100 qualification for automotive sensor signal conditioning and precision power supply feedback loops.
For engineers reviewing the TSB182IYST datasheet, TSB182IYST pinout, TSB182IYST application, or TSB182IYST equivalent, key selection criteria include ultra-low offset drift (≤100 nV/°C), rail-to-rail output swing within 30 mV of rails at 5 V, low 650 µA per-channel quiescent current, and SO8 package compatibility with industrial temperature range (-40 °C to 125 °C).
Technical Context
The TSB182 employs a 400 kHz chopper architecture that continuously corrects DC input offset and 1/f noise by modulating the input signal and demodulating it after amplification, enabling near-zero long-term drift. Its internal notch filter suppresses chopping ripple to levels comparable with broadband noise (24 nV/√Hz).
EMI resilience is achieved via integrated 1 kΩ + 1.6 pF RC filters on both inputs, yielding >40 dB rejection from 10 MHz to 1 GHz. Input protection includes anti-parallel diodes limiting differential voltage to ±0.7 V and ESD diodes rated to 4 kV HBM on all pins.

| Output swing | Rail-to-rail - delivers 30 mV from negative rail and 20 mV from positive rail at 5 V supply, maximizing dynamic range |
| Quiescent current | 650 µA per channel - enables dual-opamp precision signal chain in space-constrained, low-power applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB181IYST | Single-channel version with identical specs; same SO8 footprint but only one op-amp per package | Used where board space permits discrete channel placement or where channel isolation is prioritized over density | Select when needing single-channel flexibility or PCB layout simplification without dual-channel crosstalk concerns |
| TSB612IST | Lower quiescent current (350 µA/channel) but reduced GBW (1.5 MHz) and higher offset (75 µV max) | Suitable for always-on battery-powered sensors where power dominates speed/accuracy trade-offs | Choose for ultra-low-power applications accepting 3× higher offset and half the bandwidth of TSB182IYST |
Compared with TSB182IYST, TSB181IYST offers identical precision in a single-channel form factor-ideal for non-dense layouts-while TSB612IST trades 65% lower current for 50% less bandwidth and 3.75× higher offset, targeting energy-constrained rather than accuracy-critical designs.

FAQ
What is the maximum capacitive load the TSB182IYST can drive without oscillation?
TSB182IYST is characterized to drive up to 1 nF capacitive load without sustained oscillation, as verified in the datasheet's "Capacitive load drive" specification. For loads exceeding 100 pF, a series resistor (Riso) of 10–100 Ω placed directly at the output pin is recommended to maintain phase margin above 54° and prevent peaking in step response.
Does the TSB182IYST require external compensation for unity-gain stability?
No external compensation is required-the TSB182IYST is internally compensated for unity-gain stability across its full 4–36 V supply range and -40 °C to 125 °C temperature range. Phase margin remains ≥54° with 10 kΩ load and 100 pF capacitance, per datasheet Figure 27 and Table 3–5 AC performance data.
Can the TSB182IYST be used as a comparator?
While not optimized for comparator use, TSB182IYST can function as a slow comparator in degraded mode if input differential voltage is limited to ±0.7 V via external resistors (per Section 5.2). Output response time exceeds 1 µs for large steps, and internal chopping may cause output ripple during saturation-dedicated comparators are preferred for timing-critical applications.
How does the chopper frequency affect system-level noise performance?
The 400 kHz chopper frequency introduces negligible in-band noise due to internal notch filtering; residual ripple is suppressed to ≤620 nVpp (0.1–10 Hz) and broadband noise remains 24 nV/√Hz at 1 kHz. System-level noise is dominated by resistor thermal noise and layout-induced pickup-not chopper artifacts-when PCB layout follows recommended grounding and decoupling practices.
