Product details
Overview
TSB182IDT from STMicroelectronics is a dual-channel, 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 TSB182IDT datasheet, TSB182IDT pinout, TSB182IDT application, or TSB182IDT equivalent, key selection criteria include ultra-low offset drift (≤100 nV/°C), EMI-hardened inputs, 4 kV HBM ESD rating, extended -40 °C to 125 °C operation, and SO8 package compatibility with industrial sensor signal conditioning and automotive battery monitoring systems.
Technical Context
The TSB182IDT employs a 400 kHz chopper architecture that continuously corrects DC input offset and 1/f noise, enabling stable precision over temperature without external trimming. Its dual-channel layout supports independent signal paths with matched performance across channels.
It integrates on-die EMI filters (1 kΩ + 1.6 pF per input) tuned for >100 MHz rejection and anti-parallel input diodes limiting differential voltage to ±0.7 V. The amplifier maintains stability driving up to 1 nF capacitive loads and achieves 54° phase margin at 36 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±20 µV max at 25 °C - enables <0.01% error in 2 V full-scale current-sense applications |
| Gain Bandwidth Product | 3 MHz - supports closed-loop bandwidths up to ~280 kHz in unity-gain stable configuration |
| Slew Rate | 2 V/µs - ensures <7 µs settling to 0.1% for 10 V step, critical for fast transient response in battery monitors |
| Supply Voltage Range | 4 to 36 V - covers 12 V automotive, 24 V industrial, and wide-input power supply monitoring rails |
| Input Voltage Noise | 24 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., strain gauges, thermopiles) |
| Common-Mode Rejection | 150 dB max at 36 V - rejects >99.99997% of common-mode interference in high-side current sensing |
| Temperature Range | -40 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
| ESD Rating | 4 kV HBM - withstands handling and board-level electrostatic events without latch-up or parametric shift |
Pinout & Package
TSB182IDT is supplied in an SO8 (Small Outline Integrated Circuit, 8-pin) package with standard 1.27 mm pitch and exposed pad for thermal enhancement. Pin numbering follows JEDEC MS-012AC, top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC+ | Positive supply rail | Accepts 4–36 V; decoupling capacitor required within 1 cm for stability |
| 2: VCC− | Negative supply rail / ground reference | Must be connected to system ground or negative rail; serves as common return for both channels |
| 3: OUT1 | Channel 1 output | Rail-to-rail swing: within 30 mV of VCC− and 20 mV of VCC+ at 5 V supply |
| 4: IN1− | Inverting input, Channel 1 | Protected by anti-parallel diodes; differential voltage limited to ±0.7 V |
| 5: IN1+ | Non-inverting input, Channel 1 | EMI-filtered (1 kΩ + 1.6 pF); bias current ≤500 pA at 25 °C |
| 6: OUT2 | Channel 2 output | Electrically isolated from OUT1; identical AC/DC specs and load drive capability |
| 7: IN2− | Inverting input, Channel 2 | Matched to IN1−; enables dual-sensor differential amplification without inter-channel crosstalk |
| 8: IN2+ | Non-inverting input, Channel 2 | Independent EMI filter; supports separate gain-setting networks per channel |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | 400 kHz internal clock eliminates 1/f noise and reduces offset drift to ≤100 nV/°C over full temperature range |
| Rail-to-rail output | Drives within 30 mV of either rail at 5 V supply, maximizing dynamic range in single-supply systems |
| EMI-hardened inputs | Integrated RC filters (1 kΩ + 1.6 pF) suppress radiated noise up to 2.4 GHz, validated per Figure 46 |
| AEC-Q100 Grade 1 | Qualified for automotive applications requiring operation from -40 °C to +125 °C ambient |
| Low quiescent current | 650 µA per channel enables dual-opamp precision in power-constrained modules (e.g., battery management ICs) |
| Capacitive load drive | Stable with ≥1 nF load-eliminates need for isolation resistors in ADC driver or filter buffer stages |

Use Scenario: High-side shunt-based measurement of 12 V/24 V battery pack current in EV BMS or ADAS power domains. IC Role / Device Role / Timing Role: Dual-channel precision amplifier: one channel conditions shunt voltage, second channel buffers reference or provides redundancy. Use Value: ±20 µV offset enables <1 mA resolution at 100 mΩ shunt; AEC-Q100 and 125 °C rating ensure reliability in under-hood placement. |
Use Scenario: Isolated current measurement in PLC analog input modules using low-value shunts (e.g., 5 mΩ). IC Role / Device Role / Timing Role: First-stage gain amplifier with rail-to-rail output driving SAR ADC input; second channel used for offset calibration path. Use Value: 3 MHz GBW supports >200 kSPS sampling with <0.1% gain error; 24 nV/√Hz noise preserves 16-bit ENOB at 100 kHz bandwidth. |
| High-Voltage Power Supply Feedback | Strain Gauge Signal Conditioning |
|
Use Scenario: Precision feedback loop for 36 V industrial SMPS where output regulation requires sub-mV accuracy. IC Role / Device Role / Timing Role: Error amplifier comparing regulated output to reference; operates from same 36 V rail with no auxiliary supply. Use Value: 36 V absolute max rating and 150 dB CMRR reject ripple and switching noise; 2 V/µs slew rate prevents loop instability during load transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, chopper-stabilized op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB181IDT | Single-channel version with identical specs (20 µV VIO, 3 MHz GBW, SO8/SOT23-5) | Used where space or channel count constraints favor single-amplifier integration | Select when only one precision channel is needed; shares same footprint options and qualification status |
| TSB612IST | Lower quiescent current (380 µA/ch), reduced GBW (1.7 MHz), same 20 µV VIO and AEC-Q100 | Better suited for always-on, ultra-low-power automotive modules where speed is secondary to current draw | Choose for battery-backed systems requiring <1 mA total dual-channel supply current at 125 °C |
Compared with TSB182IDT, TSB181IDT saves board area but lacks channel redundancy, while TSB612IST trades 43% bandwidth and 270 µA/ch current savings for relaxed speed requirements-making it optimal for static-signal automotive sensors but unsuitable for fast current-loop feedback.

FAQ
What is the maximum capacitive load the TSB182IDT can drive without oscillation?
The TSB182IDT is characterized to remain stable with up to 1 nF capacitive load at the output, as verified in Table 3–5 and Figure 41–43 of DS14357. Driving larger loads requires an isolation resistor (≥10 Ω) between amplifier output and capacitance, or use of the amplifier in a follower configuration with careful PCB layout to minimize parasitic capacitance.
Does the TSB182IDT require external filtering for EMI immunity?
No external filtering is required-the device integrates optimized on-die RC EMI filters (1 kΩ + 1.6 pF per input) that provide >40 dB suppression from 100 MHz to 2.4 GHz, as shown in Figure 46. These filters are designed to maximize EMI rejection while preserving stability and adding negligible noise or phase shift below 100 kHz.
Can the TSB182IDT be used as a comparator?
While not optimized for comparator use, the TSB182IDT can operate in open-loop mode with caution: input differential voltage must be limited to ±0.7 V via external series resistors (per Section 5.2), and output recovery from saturation takes ~1 µs (Table 3–5). For dedicated comparator functions, ST recommends TS881 or TLV3201 series instead.
How does the chopper architecture affect low-frequency signal integrity?
The 400 kHz chopper introduces minimal residual ripple (<620 nVpp, 0.1–10 Hz), suppressed by an internal notch filter to levels comparable with broadband noise. In typical sensor applications (e.g., strain gauges, RTDs), this ripple is buried beneath system noise floor and does not impact DC or sub-10 Hz measurements-verified in Figures 35–36 and Section 5.1.
