EVAL-ADA4523-1ARMZ, Primary Side 2 SMA to BNC male cables DOCUMENTS NEEDED ADA4523-1 data sheet GENERAL DESCRIPTION The EVAL-ADA4523-1ARMZ allows the evaluation of the ADA4523-1 single-channel, 8-lead, micro small outline package (MSOP) operational amplifier. The ADA4523-1 in this evaluation board is configured as a noninverting amplifier with a gain of 101. The ADA4523-1 has a typical gain bandwidth product of 4 MHz. When using a gain of 101, the useable bandwidth of the ADA4523-1 is limited to approximately 39.6 kHz. This limitation in bandwidth acts as a low-pass filter that rejects the artifacts generated by the 330 kHz internal chopping frequency Figure 2. EVAL-ADA4523-1ARMZ, Secondary Side of the ADA4523-1. The EVAL-ADA4523-1ARMZ mainly consists of 0805 sized The EVAL-ADA4523-1 layout lessens the thermocouple effects resistors and capacitors to ensure simple installation except for of the trace and components that introduce offset voltages the bypass capacitors. The 10 F bypass capacitors (C1 and C4) greater than the maximum offset voltage of the ADA4523-1 by have a 2220 package size to accommodate a higher voltage carefully constructing the nodes connected to the inverting and rating because the ADA4523-1 has a maximum supply of 55 V. noninverting inputs. The ADA4523-1 also features a shutdown mode for low power applications. Test point provisions for the For full details on the ADA4523-1, see the ADA4523-1 data and SD COM pins are placed on the EVAL-ADA4523- SD sheet, which must be consulted in conjunction with this user 1ARMZ to easily use the shutdown function. guide when using the EVAL-ADA4523-1ARMZ.
