DC593A

DC593A demonstration circuit simplifies the evaluation of the LT1637CDD op amp in the tiny, 3mm × 3mm, DFN (Dual in-line, Flat, No-leads) chip-scale package. Electrical performance of this LT1637 is the same as previous versions. This version is only a packaging enhancement. An evaluation circuit can easily be built on this board without handling the tiny DFN device. Pads are provided for adding external components and holes are available for jumpers, signal I/O and supply wires. Supply bypass capacitors are already on the board. Alternatively adding two 4-pin headers (0.1inch (2.54mm) spacing) converts the board to a standard 8-pin DIP format for use with a socket on a second circuit board. The backside of this evaluation board is void of metal to allow wiring into an existing system with the board resting on top of other components.
