Features - 0V to 76V input mon mode - Low 8μV (typ) input offset voltage - Low 0.1% (max) gain error - Gain options G = 10V/V (CSA231-10) G = 20V/V (CSA231-20) G = 50V/V (CSA231-50) G = 100V/V (CSA231-100) - SOIC-8 package - TSSOP-8 package 2. APPLICATIONS - Base stations and munication equipment - Power management systems - Server backplanes - Industrial control and automation - Battery current sensing 3. DESCRIPTION The CSA231 bidirectional high-side current-sense amplifier has precision accuracy specifications of VOS less than 10μV (typ) and gain error less than 0.1% (max). The CSA231 Features an input mon-mode voltage range from 0V to 76V with 90k Hz of smallsignal bandwidth, which makes it ideal for interfacing with an ADC for multichannel multiplexed data acquisition systems. The CSA231 operates over the - 40°C to 125°C temperature range. See Table 1 for the order information. VCM = 0V to 76V RS+ RSENSE RS- System Load VDD = 2.7V to 5.5V + VDD CSA231 OUT REF1 REF2 -...
