Product details
Overview
TSB182IST from STMicroelectronics is a dual, high-precision, chopper-stabilized operational amplifier with rail-to-rail output, 20 µV max input offset voltage at 25 °C, 3 MHz gain bandwidth product, and operation across 4–36 V supply. It delivers 2 V/µs slew rate, 24 nV/√Hz input voltage noise, and AEC-Q100 qualification for automotive powertrain and body electronics.
For engineers reviewing the TSB182IST datasheet, TSB182IST pinout, TSB182IST application, or TSB182IST equivalent, this device supports precision current sensing in 12 V/24 V automotive systems, high-accuracy voltage monitoring in industrial DC-DC converters, and low-drift signal conditioning in battery management units where offset drift ≤100 nV/°C and EMI-hardened performance are critical.
Technical Context
The TSB182IST employs a 400 kHz chopper architecture to eliminate 1/f noise and minimize input offset drift, enabling stable DC accuracy over temperature. Its dual-channel design shares no internal coupling between amplifiers, supporting independent signal paths with matched AC performance.
It integrates on-die EMI filters (1 kΩ + 1.6 pF per input) targeting 10 MHz–2.4 GHz interference rejection, and features anti-parallel input diodes limiting differential voltage to ±0.7 V - requiring external series resistors if used in comparator mode or exposed to fast large-signal transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 20 µV max at 25 °C - enables sub-0.1% error in 100 mV full-scale current sense applications |
| Gain bandwidth product | 3 MHz - supports closed-loop bandwidth up to ~280 kHz with G = 10, suitable for fast feedback in switching regulators |
| Slew rate | 2 V/µs - ensures <7 µs settling for 10 V step (0.1%), critical for transient response in motor control loops |
| Supply voltage range | 4–36 V - operates directly from automotive battery (9–16 V) or industrial 24 V rails without LDO pre-regulation |
| Input voltage noise | 24 nV/√Hz at 1 kHz - maintains SNR > 90 dB in 20 kHz audio-band sensor interfaces |
| EMI rejection | Integrated RC filter (1 kΩ + 1.6 pF) - suppresses radiated RF interference above 100 MHz without external components |
| Temperature range | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1, validated for under-hood engine control modules |
Pinout & Package
TSB182IST is supplied in SO8 (Small Outline Integrated Circuit, 150 mil width) package with standard 1.27 mm pitch. Pin 1 is marked by a dot or notch; top view orientation follows JEDEC MS-012.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC+ | Positive supply terminal for both amplifiers; must be decoupled with ≥100 nF ceramic capacitor near pin |
| 2 | VCC− | Negative supply terminal (GND for single-supply use); shared reference for all internal circuitry |
| 3 | OUT1 | Output of Channel 1; rail-to-rail swing within 30–200 mV of rails depending on load and supply |
| 4 | IN1− | Inverting input of Channel 1; protected by anti-parallel diodes limiting differential voltage to ±0.7 V |
| 5 | IN1+ | Non-inverting input of Channel 1; same ESD and differential voltage protection as IN1− |
| 6 | OUT2 | Output of Channel 2; electrically isolated from OUT1, supports independent load driving |
| 7 | IN2− | Inverting input of Channel 2; identical protection and bias characteristics as IN1− |
| 8 | IN2+ | Non-inverting input of Channel 2; matches IN1+ in offset, bias current, and CMRR performance |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized architecture | 400 kHz chopping frequency eliminates 1/f noise and reduces input offset drift to ≤100 nV/°C over full temperature range |
| Rail-to-rail output stage | Drives loads to within 30 mV of VCC− and 20 mV of VCC+ at 5 V supply, enabling full dynamic range utilization in low-voltage systems |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications up to +125 °C ambient, including engine control, ADAS power supplies, and HVAC actuators |
| EMI-hardened inputs | On-chip 1 kΩ + 1.6 pF RC filters reduce RF rectification errors by >20 dB across 100 MHz–1 GHz band |
| High PSRR and CMRR | 138 dB supply rejection and 150 dB common-mode rejection at DC ensure immunity to supply ripple and ground bounce in noisy environments |

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 |
|---|---|---|---|
| TSB612IST | Lower quiescent current (350 µA vs. 650 µA), reduced GBW (1.5 MHz), same 20 µV offset and AEC-Q100 rating | Better suited for always-on battery-powered modules where power budget <500 µA/channel is mandatory | Select when supply current is constrained and 1.5 MHz bandwidth suffices for loop stability |
| TSB712IST | Rail-to-rail input and output, higher GBW (10 MHz), higher offset (75 µV max), same 36 V supply and -40 °C to 125 °C range | Required for unity-gain stable configurations with capacitive loads or high-speed multiplexed sensor arrays | Choose when input common-mode range must include VCC− and system demands >5 MHz small-signal bandwidth |
Compared with TSB182IST, TSB612IST trades bandwidth for lower power in static-sensing roles, while TSB712IST expands input flexibility and speed at the cost of offset accuracy - making TSB182IST optimal for applications demanding best-in-class DC precision with moderate AC performance.

FAQ
What is the maximum capacitive load the TSB182IST can drive without oscillation?
The TSB182IST is characterized to drive up to 1 nF capacitive load without sustained oscillation, as verified in DS14357 Table 3–5 under "Cload Capacitive load drive". For loads >100 pF, adding a small series resistor (10–50 Ω) between output and load improves phase margin and suppresses peaking, especially in unity-gain configurations.
Can the TSB182IST be used as a comparator?
Yes, but with restrictions: input differential voltage must not exceed ±0.7 V due to internal anti-parallel diodes, and continuous input current must remain below 10 mA. A series resistor ≥1 kΩ is required on each input when used in open-loop comparator mode to limit current and prevent latch-up or parametric shift.
How does the chopper architecture affect output behavior during fast transients?
At input step edges, the TSB182IST exhibits converging output steps and low-amplitude triangular ripple (~10 µVpp) due to its 400 kHz chopping clock and notch-filter reconstruction. This is visible in Figures 37–40 of DS14357 and is inherent to chopper stabilization - not a fault, but a trade-off for ultra-low drift and noise.
Is the TSB182IST pin-compatible with other SO8 dual op amps like the LM358 or TL072?
No - TSB182IST uses a non-standard SO8 pinout: VCC+ and VCC− are on pins 1 and 2, unlike industry-standard dual op amps where VCC+ is pin 8 and VCC− is pin 4. Direct replacement requires PCB layout revision; refer to Figure 2 in DS14357 for exact pin mapping.
