The LT1215 is a dual, single supply precision op amp with a 23MHz gain-bandwidth product and a 50V/µs slew rate. The LT1216 is a quad version of the same amplifier. The DC precision of the LT1215/LT1216 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers.The LT1215/LT1216 will operate on any supply greater than 2.5V and less than 36V total. These amplifiers are specified on single 3.3V, single 5V and ±15V supplies, and only require 5mA of quiescent supply current per amplifier. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The minimum output drive is 30mA, ideal for driving low impedance loads.Note: For applications requiring less slew rate, see the LT1211/LT1212 andLT1213/LT1214 data sheets.Applications 2.5V Full-Scale 12-Bit Systems: VOS ­ < 0.75 LSB 10V Full-Scale 16-Bit Systems: VOS ­ < 3 LSB Active Filters Photo Diode Amplifiers DAC Current to Voltage Amplifiers Battery-Powered Systems

The LT1620 simplifies the design of high performance, controlled current battery charging circuits when used in conjunction with a current mode PWM controller IC.The LT1620 regulates average output current independent of input and output voltage variations. Output current can be easily adjusted via a programming voltage applied to the LT1620’s PROG pin.Most current mode PWM controllers have limited output voltage range because of common mode limitations on the current sense inputs. The LT1620 overcomes this restriction by providing a level-shifted current sense signal, allowing a 0V to 32V output voltage range.The 16-pin version of the LT1620 contains a programmable low charging current flag output. This output flag can be used to signal when a Li-Ion battery charging cycle is nearing completion.The LT1621 incorporates two fully independent current control circuits for dual loop applications.Applications High Current Battery Chargers High Output Voltage DC/DC Converters Constant Current Sources Overcurrent Fault Protectors

The MAX4373/MAX4374/MAX4375 low-cost, micropower, high-side current-sense supervisors contain a high-side current-sense amplifier, bandgap reference, and comparator with latching output. They feature a voltage output that eliminates the need for gain-setting resistors, making them ideal for today's notebook computers, cell phones, and other systems where battery/DC current monitoring is critical. High-side current monitoring is especially useful in battery-powered systems since it does not interfere with the ground path of the battery charger.

In addition, the MAX4374/MAX4375 contain a second comparator for use in window-detection functions. The MAX4373/MAX4374/MAX4375 are available in three different gain versions (T = +20V/V,F = +50V/V, H = +100V/V) and use an external sense resistor to set the sensitivity of the input voltage to the load current.
