TLV197-Q1, TLV2197-Q1, TLV4197-Q1
SBOS935B –APRIL 2020–REVISED JULY 2020
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.

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.
