TLVx197-Q1 Automotive, High-Voltage, Precision, Rail-to-Rail In, Rail-to-Rail Out Op Amp 1 Features 3 Description
• AEC-Q100 qualified for automotive applications: The TLV197-Q1, TLV2197-Q1 and TLV4197-Q1 1 (TLVx197-Q1) family of devices are part of a new – Temperature grade 1: –40°C to +125°C, TA generation, of low-cost, 36-V, automotive-qualified, • Low offset voltage: ±500 µV (maximum) operational amplifiers. The TLVx197-Q1 family uses a • Low noise: 5.5 nV/√Hz at 1 kHz method of package-level trim for offset and offset temperature drift implemented during the final steps • High common-mode rejection: 140 dB of manufacturing after the plastic molding process. • Low bias current: ±5 pA This method minimizes the influence of inherent input • Rail-to-rail input and output transistor mismatch, as well as errors induced during • Wide bandwidth: 10-MHz GBW package molding. • High slew rate: 20 V/µs Good dc precision and ac performance including rail- • Low quiescent current: 1 mA per amplifier to-rail input/output, an optimized cost structure, and AEC-Q100 grade 1 qualification, make this family an • Wide supply: ±2.25 V to ±18 V, 4.5 V to 36 V excellent choice for low-side current-sensing and • EMI/RFI filtered inputs signal-conditioning applications in the automotive • Differential input-voltage range to supply rail space. • High capacitive load drive capability: 1 nF More unique features, such as a differential input- • Industry-standard package: voltage range to the supply rail, a high output current (±65 mA), a heavy capacitive load drive of up to 1 nF, – Single channel in very small 8-pin VSSOP and a high slew rate (20 V/µs), make these devices a – Dual channel in 8-pin VSSOP robust, high-performance operational amplifier family – Quad channel in 14-pin TSSOP for high-voltage automotive applications. The TLVx197-Q1 family of op amps is available in
