LINEAR TECHNOLOGY LT6011/LT6012 Manual
LT6011/LT6012 is a low noise, high precision input performance, low power consumption, rail to rail output swing precision operational amplifier. Input offset voltage can be trimmed to less than 60μV. Low drift and excellent long-term stability guarantee high accuracy over temperature and time. The maximum input bias current of 300pA and the minimum voltage gain of 120dB further maintain this precision over operating conditions. LT6011/LT6012 can operate at any power supply voltage from 2.7V to 36V and draw only 135μA of supply current on a 5V supply. The output swings to within 40mV of either supply rail, making the amplifier a good choice for low voltage single supply applications. LT6011/LT6012 are specified at 5V and ±15V supplies and from -40°C to 85°C. LT6011 (dual) is available in SO-8, MS8 and space saving 3mm x 3mm DFN package.

LINEAR TECHNOLOGY LTC1733 Manual
LTC1733 is a single-chip lithium-ion battery constant-current/constant-voltage linear charger with an on-chip power MOSFET. Internal thermal feedback regulates the charge current to limit die temperature during high power operation or high ambient temperature conditions. No external current sense resistor is needed and no blocking diode is required due to the internal MOSFET architecture. The charge current and charge time can be set externally with a single resistor and capacitor.

LINEAR TECHNOLOGY LT4250L/LT4250H Manual
The LT4250L/LT4250H is a negative 48V hot swap controller that allows a board to be safely inserted and removed from a live backplane. By controlling the gate voltage of an external N-channel pass transistor, inrush current is limited to a programmable value. If the input voltage is less than the programmable undervoltage threshold or greater than the overvoltage threshold, the pass transistor is turned off. A programmable current limit protects the system against shorts. After a 500µs timeout, the current limit activates the electronic circuit breaker. The PWRGD (LT4250L) or PWRGD (LT4250H) signal can be used to directly enable a power module. The LT4250L is designed for modules with a low enable input and the LT4250H for modules with a high enable input. The LT4250L/LT4250H are available in 8-pin PDIP and SO packages.

LINEAR TECHNOLOGY LTC3831 Manual
This document introduces the LTC3831, a high power, high efficiency DDR memory termination switching regulator controller. The device uses a synchronous switching architecture with N-channel MOSFETs, and the output voltage is equal to 1/2 of the external supply or reference voltage. The LTC3831 can sense output current and regulate it through the drain-source resistance of the upper N-channel MOSFET, thereby providing adjustable current limit without a current sense resistor. The device can operate with a supply voltage as low as 3V and with a maximum duty cycle of >91%. It includes a fixed frequency PWM oscillator for low output ripple operation.
LINEAR TECHNOLOGY LT3012 Manual
LT3012 is a high voltage, micropower, low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (operating 40µA, shutdown 1µA) makes the LT3012 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3012 include the ability to operate with very small output capacitors. The regulator is stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available with an adjustable output with a 1.24V reference voltage. The LT3012 regulator is available in the 16-lead TSSOP and 12 pin low profile (0.75mm) (4mm × 3mm) DFN packages with an exposed pad for enhanced thermal handling capability.

LINEAR TECHNOLOGY LTC6240/LTC6241/LTC6242 Manual
The LTC6240/6241/LTC6242 series are low noise, low offset, unity gain stable CMOS op amps featuring 1pA of input bias current. Input bias current is guaranteed to be 1pA max on the single LTC6240. The 0.1Hz to 10Hz noise of only 550nVP-P, along with an offset of just 125µV are significant improvements over traditional CMOS op amps. Additionally, noise is guaranteed to be less than 10nV/√Hz at 1kHz. An 18MHz gain bandwidth, and 10V/µs slew rate, along with the wide supply range and low input capacitance, make them perfect for use as fast signal processing amplifiers. These op amps have an output stage that swings within 30mV of either supply rail to maximize the signal dynamic range in low supply applications. The input common mode range extends to the negative supply. They are fully specified on 3V and 5V, and an HV version guarantees operation on supplies up to ±5V. The LTC6240 is available in the 8-pin SO and the 5-pin SOT-23 packages. The LTC6241 is available in the 8-pin SO, and for compact designs it is packaged in a tiny dual fine pitch leadless (DFN) package.
