previously I'm using more than 40 numbers AD8236 in a instrument , the reason for choosing this Low power consumption ,so the battery charge can stand up to our requirement time , but now AD8236 is out of stock , I'm searched for other IN-amp which has low power consumption ,but I didn't get any other IC which consume Less power , all are out stock , can anyone give a solution for that or any other IC's to replace AD8236
