The – INA203 = 20 V/V INA203, INA204, and INA205 can sense drops across shunts at common-mode voltages from –16 V – INA204 = 50 V/V to 80 V. The INA203, INA204, and INA205 are – INA205 = 100 V/V available with three output voltage scales: 20 V/V, 50 • Dual Comparators: V/V, and 100 V/V, with up to 500-kHz bandwidth. – Comparator 1 With Latch The INA203, INA204, and INA205 also incorporate – Comparator 2 With Optional Delay two open-drain comparators with internal 0.6-V references. On 14-pin versions, the comparator • Common-Mode Range: –16 V to 80 V references can be overridden by external inputs. • High Accuracy: 3.5% (Maximum) Over Comparator 1 includes a latching capability, and Temperature Comparator 2 has a user-programmable delay. 14-pin • Bandwidth: 500 kHz versions also provide a 1.2-V reference output. • Quiescent Current: 1.8 mA The INA203, INA204, and INA205 operate from a • Packages: SO-14, TSSOP-14, VSSOP-10 single 2.7-V to 18-V supply. They are specified over the extended operating temperature range of –40°C to 125°C. 2 Applications • Notebook Computers Device Information (1) • Cell Phones PART NUMBER PACKAGE BODY SIZE (NOM) • Telecom Equipment SOIC (14) 8.65 mm × 3.91 mm INA203, • Automotive INA204, VSSOP (10) 3.00 mm × 3.00 mm INA205 • Power Management TSSOP (14) 5.00 mm × 4.40 mm • Battery Chargers (1) For all available packages, see the orderable addendum at the end of the data sheet. • Welding Equipment SPACE SPACE Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
