Click here for production status of specific part numbers. Evaluates: MAX40077, MAX40089 MAX40089 Evaluation Kit General Description Quick Start The MAX40089 evaluation kit (EV kit) is a fully assembled Required Equipment and tested circuit board that contains all the components Before beginning, the following equipment is needed: necessary to evaluate both MAX40077 and MAX40089 MAX40089 EV kit dual channel op amps. 2.7V to 5.5V, 100mA DC power supply The MAX40089 EV kit printed circuit board (PCB) comes installed with MAX40089AUT+ in an 8-MAX package. Precision voltage calibrator The device is a dual-channel, rail-to-rail output op amp 2 digital multimeters offering 10MHz Gain Bandwidth product (MAX40077) and Procedure 42MHz Gain Bandwidth product (MAX40089). The EV kit The EV kit is fully assembled and tested. Follow the steps operates from a single 2.7V to 5.5V DC power supply or from 1.35V to 2.75V split supply. below to verify board operation. Caution: Do not turn on power supplies until all connections are completed Features and turn on V , V supplies before turning on voltage DD SS sources on the input pins. +2.7V to +5.5V Supply Voltage Range Across V DD and V 1) Make sure JU1 and JU4 jumpers are installed in 1-2 SS and 1-4 position, respectively, before applying supply 42MHz Gain Bandwidth Product (MAX40089) voltage. 10MHz Gain Bandwidth Product (MAX40077) 2) Have JU5 installed for single-supply operation. Ultra-Low Distortion (0.0002% with 1k load) Proven PCB Layout 3) Connect positive terminal of the +5V supply to the VDD test point and the GND terminal of supply to the Fully Assembled and Tested VSS test point. 4) Connect the positive terminal of the precision voltage Ordering Information appears at end of data sheet. source to the INA+ and INB+ test point and negative terminal to GND test point. 5) Connect 2 Digital Multimeters(DMM) to monitor the voltage on the OUTA and OUTB test points. 6) Turn on the 5V power supply connected to VDD test point and turn on the precision voltage source on INA+, INB+ test points and set 0.1V. Observe the output at the OUTA and OUTB test points on the Multimeters. DMMs should approximately read 1V. 7) Also, now vary precision voltage source on inputs INA+, INB+ between 0V to 0.45V and see if DMMs on OUTA and OUTB test points is gained up by a factor of 10V/V to the voltage applied on input. Once above steps are confirmed, EV kit is tested for functionality. 319-100180 Rev 1 5/18Evaluates: MAX40077, MAX40089 MAX40089 Evaluation Kit MAX40089 EV Kit Board Photo Maxim Integrated 2 www.maximintegrated.com
