LTC6915 Evaluation Kit
Linear Technology Inc.
Description
A DC1070 demonstration circuit features the LTC6915 IC, a programmable gain instrumentation amplifier. The LTC6915 is a precision programmable gain instrumentation amplifier. The gain can be programmed to0,1,2,4,8,16,32,64,128,256,512,1024,2048, or 4096 through a parallel or serial interface. The offset is below 10V with a temperature drift of less than 50nV/°C. The LTC6915 uses charge balanced sampled data techniques to convert a differential input voltage into a single ended signal that is in turn amplified by a zero-drift operational amplifier. The LTC6915 can be used in single power supply applications as low as 2.7V,or with dual ±5V supplies. The DC1070 contains an LTC6915, an LCD display and switches and a PIC (micro-controller). The PIC reads the settings of the switches, sends a parallel or a serial control word to the LTC6915 and displays the PG A gain on the LCD display. The LTC6915 on the DC1070 can be control-ed with an external parallel or serial digital control by moving wire jumpers A-F from position 1-2 to 2-3 and connecting six external digital control lines to on board turrets.
