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 SC100.

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. FEATURES •= Trimmed bandgap design (0.8%, 0.32% for •= Wide operating current range 20µA to 20mA •= Low dynamic impedance (0.2Ω) •= SO-8 package APPLICATIONS •= •= •= •= Micropower circuitry Portable meters Battery powered systems Temperature sensors SC1004A version) ORDERING INFORMATION BLOCK DIAGRAM VOLTAGE 1.235 V SC1004CS8-1.2.TR SC1004ACS8-1.2.TR (1) INITIAL ACCURACY 2.5 V Cathode SC1004CS8-2.5.TR - ±0.8% ±0.32% Notes: (1) Only available in tape and reel packaging.
