DESCRIPTIO

Operates with Inputs Above V⁺

The LT^®1782 is a 200kHz op amp available in the small

SOT-23 package that operates on all single and split

supplies with a total voltage of 2.5V to 18V. The amplifier

drawslessthan55µAofquiescentcurrentandhasreverse

battery protection, drawing negligible current for reverse

supply voltages up to 18V.

Rail-to-Rail Input and Output

Micropower: 55µA Supply Current Max

■

Operating Temperature Range: –40°C to 125°C

Low Profile (1mm) ThinSOT^TMPackage

Low Input Offset Voltage: 800µV Max

Single Supply Input Range: 0V to 18V

High Output Current: 18mA Min

Specified on 3V, 5V and ±5V Supplies

Output Shutdown on 6-Lead Version

Reverse Battery Protection to 18V

High Voltage Gain: 1500V/mV

Gain Bandwidth Product: 200kHz

Slew Rate: 0.07V/µs

The input range of the LT1782 includes ground, and a

unique feature of this device is its Over-The-Top^TMopera-

tion capability with either or both of its inputs above the

positive rail. The inputs handle 18V both differential and

common mode, independent of supply voltage. The input

stage incorporates phase reversal protection to prevent

false outputs from occurring even when the inputs are 9V

below the negative supply.

The LT1782 can drive loads up to 18mA and still maintain

rail-to-rail capability. A shutdown feature on the 6-lead

version can disable the part, making the output high

impedance and reducing quiescent current to 5µA. The

LT1782 op amp is available in the 5- and 6-lead

SOT-23packages.Forapplicationsrequiringhigherspeed,
