BurrĆBrown Products from Texas Instruments INA 203 INA2 03 INA 203 INA203 INA204 INA205 SBOS393 – MARCH 2007 Unidirectional Measurement Current-Shunt Monitor with Dual Comparators FEATURES COMPLETE CURRENT SENSE SOLUTION DUAL COMPARATORS: – Comparator 1 with Latch – Comparator 2 with Optional Delay COMMON-MODE RANGE: –16V to +80V HIGH ACCURACY: 3.5% (max) Over Temperature BANDWIDTH: 500kHz QUIESCENT CURRENT: 1.8mA PACKAGES: SO-14, TSSOP-14, MSOP-10 DESCRIPTION The INA203, INA204, and INA205 are a family of unidirectional, current-shunt monitors with voltage output, dual comparators, and voltage reference. The INA203, INA204, and INA205 can sense drops across shunts at common-mode voltages from –16V to +80V. The INA203, INA204, and INA205 are available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz bandwidth. The INA203, INA204, and INA205 also incorporate two open-drain comparators with internal 0.6V references. On 14-pin versions, the comparator references can be overridden by external inputs. Comparator 1 includes a latching capability, and Comparator 2 has a user-programmable delay. 14-pin versions also provide a 1.2V reference output. The INA203, INA204, and INA205 operate from a single +2.7V to +18V supply. They are specified over the extended operating temperature range of –40°C to +125°C.
