ISO106B - 70 kHz Isolation Amplifier | Texas Instruments
MPN： ISO106B ✗ 停產ISO106B 概覽
An isolation amplifier is a precision signal-conditioning component that transfers a low-level input signal across an electrically isolated barrier while preserving signal integrity. In the broader electronics hierarchy, an isolation amplifier belongs to the instrumentation-amplifier and signal-isolation categories, which are used when a measurement or control system must prevent ground loops, reject high common-mode voltage, or protect sensitive circuitry from hazardous or high-voltage environments.
The verified listing specifies a 70 kHz operating bandwidth and a 16-CDIP package for ISO106B. The CDIP designation indicates a ceramic dual-inline package with 16 leads. Other electrical details, including supply voltage, isolation withstand voltage, input range, gain, noise, input impedance, output impedance, and temperature range, were not included in the supplied source data and therefore must be confirmed from the manufacturer datasheet before design release.
Typical signal-chain uses include isolated sensor conditioning, industrial measurement interfaces, medical-instrument signal acquisition, communications isolation, and high-voltage measurement front ends. The amplifier should be selected based on the required bandwidth, common-mode range, isolation rating, supply architecture, package footprint, and whether the system requires a hermetic ceramic package rather than a plastic surface-mount package.
For PCB design, preserve the isolation barrier and observe the datasheet's recommended creepage, clearance, grounding, decoupling, and pin-routing requirements. Do not treat an isolation amplifier as an unrestricted safety barrier without verifying its rated voltage, installation category, and applicable system safety requirements. The source data identifies a 16-lead CDIP package, so through-hole layout and connector or socket mechanics may influence assembly choice.
This page synthesizes the verified distributor identity, package, bandwidth, sourcing information, and engineering limitations for ISO106B. Because the supplied evidence does not establish a manufacturer datasheet URL, pin mapping, detailed electrical limits, lifecycle status, compliance declarations, or validated drop-in replacements, those fields are intentionally marked for verification rather than inferred.

典型應用
ISO106B 適用於 6 應用s: Industrial Sensor Signal Conditioning, High-Voltage Measurement Interface, Data Acquisition and Test Equipment, Medical-Instrument Signal Acquisition, Communications and Power-Equipment Isolation, Isolated Feedback in Power and Motor Control.
Industrial Sensor Signal Conditioning
ISO106B is a candidate for isolated industrial sensor conditioning when the measured signal bandwidth is compatible with its verified 70 kHz rating. Place the device between a sensor front end and a controller or data-acquisition system so the signal crosses an isolation barrier before entering sensitive electronics. The 16-CDIP through-hole package can simplify maintenance and socketed assembly in equipment-enclosure prototypes. Verify the input range, gain, common-mode limits, supply voltage, and isolation withstand voltage from the manufacturer datasheet before selecting it for transducer excitation or process-control signals.
推薦
High-Voltage Measurement Interface
ISO106B can be evaluated for a high-voltage measurement front end when the isolation barrier must separate the sensed node from downstream processing electronics. Its verified isolation-amplifier classification makes the application architecturally appropriate, while the 70 kHz bandwidth supports moderate-bandwidth measurement channels. The actual safety and performance case depends on the unavailable isolation voltage, leakage, common-mode range, and creepage/clearance specifications. Do not infer a safe working voltage from the package or product category; verify the official electrical ratings and insulation requirements first.
推薦
Data Acquisition and Test Equipment
ISO106B is suitable for consideration in isolated data-acquisition and test equipment that needs to transfer a bounded analog signal without sharing the same ground reference as the measured equipment. The 70 kHz bandwidth can accommodate many sensor and control signals, but it does not define gain accuracy or settling time. A practical design would place ISO106B close to the analog input boundary, use shielded signal routing where appropriate, and provide regulated supplies that meet the device's unverified requirements. Prototype validation should include offset, noise, bandwidth, isolation, and temperature testing.
推薦
Medical-Instrument Signal Acquisition
ISO106B may be studied for isolated analog signal acquisition in medical equipment, but the supplied sources do not establish medical qualification, regulatory approval, or a complete safety rating. The isolation-amplifier function can help separate a patient-side signal path from processing electronics, yet the design must also satisfy leakage, dielectric-strength, creepage, clearance, and system-level risk requirements. Treat ISO106B as an engineering candidate only. A medical design requires the official datasheet, applicable safety analysis, validation testing, and a documented risk-control process before production use.
推薦
Communications and Power-Equipment Isolation
ISO106B can be evaluated for communications interface or power-equipment signal isolation when the signal bandwidth is below 70 kHz and the electrical isolation requirements are met. The part should sit between a potentially noisy or high-side source and a lower-energy logic or measurement domain, with separate return paths on each side of the barrier. Because the verified sources do not state isolation withstand voltage, working voltage, leakage current, or package creepage, engineers must not treat it as a complete safety barrier without a datasheet-based review. Bench testing should include common-mode transient and insulation checks.
推薦
Isolated Feedback in Power and Motor Control
ISO106B may be considered for an isolated feedback or monitoring channel in power-conversion and motor-control equipment, particularly where a 70 kHz-class signal bandwidth is sufficient. The device would transfer a control or measurement signal across the isolation boundary while allowing the two domains to maintain separate references. Its suitability depends on response time, propagation delay, gain, supply voltage, input range, and isolation rating, none of which are supplied here. Use it only after measuring transient behavior and confirming that the barrier meets the applicable equipment insulation requirements.

設計說明
Do not select the supply rails or bypass capacitors for ISO106B until the official datasheet provides its exact supply-voltage limits, quiescent current, and recommended decoupling. The verified sources identify the device as an isolation amplifier but do not provide those electrical values. Route each supply domain independently where required, keep high-current return paths away from the isolated input reference, and verify startup and shutdown behavior across the complete system voltage range.
Preserve the isolation barrier and follow the manufacturer's creepage, clearance, and pin-routing requirements. The supplied data does not state those dimensions, so any proposed spacing value must come from the ISO106B datasheet or the applicable system safety standard. Keep copper, solder mask, and component placement from unintentionally bridging the isolated and non-isolated domains. Because ISO106B is a 16-lead through-hole CDIP, also verify socket and connector spacing during mechanical layout.
Do not assume that any other isolation amplifier with a similar description is pin-compatible. ISO106B requires an exact comparison of all 16 pins, supply requirements, gain, bandwidth, input range, common-mode limits, isolation rating, and temperature grade. The supplied cross-reference search returned no validated drop-in substitute. A functionally similar part may require a PCB or system redesign even if its isolation function is the same.
合規資訊
The supplied search results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for ISO106B. These values must be confirmed against the exact Texas Instruments ordering code and current manufacturer declarations.
