LT1783

1.25MHz, Over-The-Top

Micropower, Rail-to-Rail Input

and Output Op Amp in SOT-23

DESCRIPTION

FEATURES

The LT^®1783 is a 1.25MHz op amp available in the small

SOT-23packagethatoperatesonallsingleandsplitsupplies

withatotalvoltageof2.5Vto18V. Theampliﬁerdrawsless

than 300μA of quiescent current and has reverse-battery

protection, drawing negligible current for reverse supply

voltages up to 18V.

Operates with Inputs Above V

Rail-to-Rail Input and Output

Micropower: 300μA Supply Current Max

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

Gain Bandwidth Product: 1.25MHz

Slew Rate: 0.42V/μs

Low Input Offset Voltage: 800μV Max

Single Supply Input Range: 0V to 18V

High Output Current: 18mA Min

The input range of the LT1783 includes ground, and a

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

tion capabilitity 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.

Speciﬁed on 3V, 5V and 5V Supplies

Output Shutdown on 6-Lead Version

Reverse-Battery Protection to 18V

High Voltage Gain: 1500V/mV

Low Proﬁle (1mm) ThinSOT™ Package

The LT1783 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

LT1783 op amp is available in the 5- and 6-lead SOT-23

packages. For applications requiring lower power, refer

to the LT1782.
