SC1004A

PRECISION SHUNT VOLTAGE REFERENCE May 1, 2000 SC1004(A) TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1004(A) is a two terminal precision voltage reference with thermal stability guaranteed over temperature. The SC1004(A) has a typical dynamic output impedance of 0.2Ω.= Active output circuitry provides a very sharp turn on characteristic - the minimum operating current is 20µA, with a maximum of 20mA. Coming with an initial tolerance of ± 0.8% (0.32% for SC1004A), and with two available voltage options (1.235V and 2.5V) in a small SO-8 package, the SC1004(A) is ideally suited for very low power circuitry such as temperature sensors and portable meters.
