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