Current Op Amp

DescripTion

The

LTC

®

6090/LTC6090-5

are high voltage, precision

monolithic operational amplifiers. The LTC6090 is unity

gain stable. The LTC6090-5 is stable in noise gain con-

figurations of 5 or greater. Both amplifiers feature high

open loop gain, low input referred offset voltage and noise,

and pA input bias current and are ideal for high voltage,

high impedance buffering and/or high gain configurations.

The amplifiers are internally protected against over-

temperature conditions. A thermal warning output,

TFLAG,

goes active when the die temperature approaches 150°C.

The output stage may be turned off with the output disable

OD.

By tying the

OD

pin to the thermal warning output

(TFLAG), the part will disable the output stage when it is

out of the safe operating area. These pins easily interface

to any logic family.

Both amplifiers may be run from a single 140V or spit

±70V power supplies and are capable of driving up to

200pF of load capacitance. They are available in either an

8-lead SO or 16-lead TSSOP package with exposed pad

for low thermal resistance.

Note 1:

Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2:

The LTC6090/LTC6090-5 is capable of producing peak output

currents in excess of 50mA. Current density limitations within the IC require

the continuous RMS current supplied by the output (sourcing or sinking)

over the operating lifetime of the part be limited to under 50mA (Absolute

Maximum). Proper heat sinking may be required to keep the junction

temperature below the absolute maximum rating. Refer to Figure 7, the

Power Dissipation section, and the Safe Operating Area section of the data

sheet for more information.

Note 3:

The LTC6090C/LTC6090I are guaranteed functional over the

operating junction temperature range –40°C to 85°C. The LTC6090H

is guaranteed functional over the operating junction temperature range

–40°C to 125°C. Specifying the junction temperature range as an operating

condition is applicable for devices with potentially significant quiescent

power dissipation.

Note 4:

The LTC6090C is guaranteed to meet specified performance from

0°C to 70°C. The LTC6090C is designed, characterized, and expected

to meet specified performance from –40°C to 85°C but is not tested or

QA sampled at these temperatures. The LTC6090I is guaranteed to meet

specified performance from –40°C to 85°C. The LTC6090H is guaranteed

to meet specified performance from –40°C to 125°C.

Note 5:

This device includes over temperature protection that is intended

to protect the device during momentary overload conditions. Operation

above the specified maximum operating junction temperature is not

recommended.

Note 6:

Input bias and offset current is production tested with ±15V

supplies. See Typical Performance Characteristics curves of actual typical

performance over full supply range.
