ISL28006 Functional Diagram
Description
The ISL28006 is a micropower, uni-directional high-side and low-side current sense amplifier featuring a proprietary rail-to-rail input current sensing amplifier. The ISL28006 is ideal for high-side current sense applications where the sense voltage is usually much higher than the amplifier supply voltage. The device can be used to sense voltages as high as 28V when operating from a supply voltage as low as 2. 7V. The micropower ISL28006 consumes only 50µA of supply current when operating from a 2. 7V to 28V supply. The ISL28006 features a common-mode input voltage range from 0V to 28V. The proprietary architecture extends the input voltage sensing range down to 0V, making it an excellent choice for low-side ground sensing applications. The benefit of this architecture is that a high degree of total output accuracy is maintained over the entire 0V to 28V common mode input voltage range. The ISL28006 is available in fixed (100V/V, 50V/V, 20V/V and Adjustable) gains in the space saving 5 Ld SOT-23 package and the 6 Ld SOT-23 package for the adjustable gain part. The parts operate over the extended temperature range from -40°C to +125°C.

- Application NotePDF 617 KB R13AN0020EU0100 Rev.1.00 Dec 18, 2023AI-generated Summary: Five essential amplifier circuits form the foundation of sensor signal conditioning: inverting amplifier, non-inverting amplifier, difference amplifier, two-op-amp instrumentation amplifier, and three-op-amp instrumentation amplifier. These circuits enable signal amplification, phase control, noise reduction, and precise differential measurement. The inverting amplifier provides phase inversion and amplification, while the non-inverting amplifier amplifies without phase change. Difference amplifiers measure voltage differences between two inputs. Two- and three-op-amp instrumentation amplifiers offer enhanced precision and common-mode noise rejection, suitable for industrial and medical applications requiring accurate sensor data processing.

- Application NotePDF 912 KB R13AN0013EU0100 Rev.1.00 Mar 09, 2022AI-generated Summary: The document explains how to measure the Common-Mode Rejection Ratio (CMRR) and Power Supply Rejection Ratio (PSRR) of current-sense amplifiers using practical bench tests. It details test setups, measurement procedures, and results for the ISL28006-100 device. CMRR quantifies the amplifier's ability to reject signals common to both inputs, while PSRR measures its ability to suppress power supply variations. The measurements show typical rejection ratios significantly exceed minimum datasheet specifications, ensuring high device performance and reliability.
- Application NotePDF 213 KB AN1567 Feb 08, 2022AI-generated Summary: The ISL28005 and ISL28006 current sense amplifiers provide unidirectional current sensing with gains of 20V/V, 50V/V, and 100V/V, including an adjustable gain version. They feature ground-sensing diagnostics to detect faults like shorts or open circuits by measuring current at ground voltage. The two-amp topology enables wide input voltage range operation with high accuracy and low power consumption. Gain selection optimizes measurement range and power dissipation. Optional transient protection components help manage voltage spikes and inrush currents. These amplifiers support compact, efficient, and accurate current monitoring.
- Application NotePDF 920 KB AN1827 Feb 07, 2022AI-generated Summary: The document discusses high-side, high-current sensing techniques using low-voltage op amps for high-voltage rails. It explains differential amplifier limitations and introduces improved circuits that use biasing schemes and buffer transistors to enhance accuracy and bandwidth. The circuits support sensing in switching supplies, including DCR sensing, and maintain functionality during load shorts. Key advantages include low power dissipation, high accuracy, and extended gain-bandwidth product.

- Application NotePDF 564 KB an1993 May 22, 2018AI-generated Summary: Voltage feedback (VFB) amplifiers use a differential input pair, a high-impedance stage, and an output buffer to convert input voltage differences into output voltage. The VFB amplifier's gain decreases at a dominant pole frequency due to compensation capacitors. Current feedback (CFB) amplifiers include a class AB input amplifier, current mirror, high-impedance stage, and output buffer. CFB amplifiers provide faster switching and higher slew rates by drawing charge/discharge currents directly from supply rails, unlike VFB amplifiers which are limited by biasing current sources.
