This paper introduces Linear Technology's latest current sense amplifiers, including the LT6105, LT6106 and LT6107. These products offer high accuracy, low power consumption, wide input voltage range, and low input bias current, making them ideal for a variety of current measurement applications.
This document introduces the LT6105, LT6106, and LT6107 family of versatile current sense amplifiers designed for accurate measurement in various electronics subsystems. The LT6105 is distinguished by its rail-to-rail inputs and wide input voltage range (-0.3V to 44V), making it suitable for monitoring programmable supplies and fuses. The LT6106 offers ease of use with low offset voltage, while the functionally identical LT6107 provides guaranteed performance at junction temperatures up to 150°C.
| Input Voltage Range (LT6105) | -0.3V to 44V |
|---|---|
| Supply Voltage Range (All Models) | 2.7V to 36V |
| Input Offset Voltage (LT6106) | 250pV |
| Power Supply Rejection Ratio (PSRR) LT6106/7 | 106dB |
| Maximum Junction Temperature (LT6107) | 150°C |
The LT6107 is functionally identical to the LT6106 but provides guaranteed performance and specifications at junction temperatures up to 150°C.
Yes, the LT6105 can be used to sense across fuses or MOSFETs without concern for an open circuit condition due to its high voltage PNP's and unique input topology.
The maximum differential input voltage for the LT6105 is 44V.
