LT1784

2.5MHz, Over-The-Top

Low Power, Rail-to-Rail Input

and Output Op Amp in SOT-23

FEATURES

DESCRIPTIO

Operates with Inputs Above V⁺

The LT^®1784 is a 2.5MHz 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

draws less than 750µA of quiescent current and has

reverse battery protection, drawing negligible current for

reverse supply voltages up to 18V.

Rail-to-Rail Input and Output

Low Profile (1mm) ThinSOT^TMPackage

■

Gain Bandwidth Product: 2.5MHz

■

Slew Rate: 2.1V/µs

■

Low Input Offset Voltage: 3.5mV Max

■

High Voltage Gain: 1000V/mV

The input range of the LT1784 includes ground, and a

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

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.

■

Single Supply Input Range: 0V to 18V

■

Specified on 3V, 5V and ±5V Supplies

■

Reverse Battery Protection to 18V

■

Low Power: 750µA Supply Current Max

■

Output Shutdown on 6-Lead Version

■

High Output Current: 15mA Min

■

Operating Temperature Range: –40°C to 85°C

APPLICATIO S

The LT1784 can drive loads up to 15mA 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

LT1784 op amp is available in the 5- and 6-lead

SOT-23packages.Forapplicationsrequiringlowerpower,
