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.

•

AEC-Q100 qualified for automotive applications:

Temperature grade 1: –40°C to +125°C, T_A

–

•

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.
