STEVAL-CCA036V1

STEVAL-CCA036V1 Demonstration board for single channel op-amp in SO8 package Data brief Description The STEVAL-CCA036V1 demonstration board is designed to help characterize single operational amplifiers in SO8 packages. With this board, the most common op-amp based circuits can be achieved. STEVAL-CCA036V1 Features • This demonstration board with its components allow it to be configured as: – Low-pass Sallen-Key circuit – High-pass Sallen-Key circuit – Differential amplifier – AC-coupled circuit – In-loop compensation circuit – Out-of-loop compensation circuit – Numerous other possible configurations not described here The board is designed for surface-mounted components and can be used to perform onboard characterization prior to the integration of STMicroelectronics’ products in your designs. Resistor and capacitor footprints are implemented for the 0805 series. A set of two decoupling capacitors have been implemented on both power supply pins so as to benefit from the maximum performances of ST products. In order to reject a wide range of frequencies, 10 nF and 4.7 µF are good values for these capacitors. • RoHS compliant June 2013 DocID024760 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com Schematic diagram 1 STEVAL-CCA036V1 Schematic diagram Z14 NA GVIn- Z4 NA GND 2mm C1 10nF VGOut VOut NA Z12 Z7 NA Vccn Z13 NA Vout_BNC Vcc+ C2 4.7uF GVcc+ Vccn C3 10nF Vout GIn+ In+ Vccn 2mm Vccp 6 V- NA Z5 Vccp 2mm 2mm Vccp DUT V+ 3 4 Vin+_BNC Z2 NA GOut Out 2 Z1 NA 7 In- GVIn+ VIn+ Z9 Z3 NA NA Z8 NA Vin-_BNC GIn- VIn- Figure 1.
