The Giddings \u0026amp; Lewis brand logo is printed on the board. The board is a large-format, high-density through-hole assembly configured for four independent servo channels labeled SERVO CHAN A, B, C, and D along the left edge. Gold-edge card connectors labeled BOARD and P1 are located along the board edges. A Burr-Brown DAC80P-CBI-V D\/A converter IC is visible on the board face. A 16.384 MHz crystal oscillator Y-1 is present. Primary analog switch ICs are Maxim DG503ACJ and DG508ACJ at IC-1 and IC-2 positions with 8819 date codes, representing a later production revision compared to Intersil IH6108CPE-populated variants of the same board. Texas Instruments TL082CP dual op-amps are present at multiple positions. NE5532 and NE5532P precision op-amps appear at IC-12, IC-32, IC-54, IC-76, and IC-82 positions. Linear Technology LT1055 precision op-amps are present at IC-69, IC-82, and IC-84. Logic ICs include SP8818A DM74LS174N, SP8812A DM74LS244N, SN74LS160AN, DM74LS161AN, SN74LS640N, SN74LS240N, DM74LS138N, DM74LS373N, SP8730A DM74LS123N, SN74LS04N, DM74LS20N, DM74LS08N, SP8552 DM74LS164N, SP8736A DM74LS73AN, SN74LS682N, and DM7406N among others. MC74F32NDS and MC74F174NDS fast logic ICs are present. Test points TP1, TP2, and GND TP9 are accessible. Physical condition shows signs of prior installation and use.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-527\u003c\/p\u003e","brand":"Giddings \u0026 Lewis Electronics","offers":[{"title":"Default Title","offer_id":48856761368816,"sku":"m00527","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/2A975B11-D403-4390-BE5D-832DDF350FFF.jpg?v=1771627234","url":"https:\/\/mroexchange.com\/products\/giddings-lewis-electronics-servo-board-pcb-assembly-501-03852-00-502-03055-00-0226-527","provider":"MRO Exchange","version":"1.0","type":"link"}
