Digital high accuracy pressure tester circuit (high-precision integrated pressure signal conditioner MAX1457)

Published:2012/11/23 2:52:00 Author:Ecco | Keyword: Digital, high accuracy , pressure tester , high-precision, integrated, pressure signal conditioner | From:SeekIC

MAX1457 selects 93C66 4096b external read-only memory E2PROM. MCS-end is pulled into a high level after geting power, and it selects the main chip. +5V power supplyprovides partial pressurefor the bias circuit by the resistor RBIAS (400k). C2, C4 and C6 are the decoupling capacitors. C1, C3, C5, C7~C11are bypass capacitors. When you take RISRC=50k Ω, excitation current is 0. 5mA.
