Additional Details

The LT1782 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 draws less than 55μA of quiescent current and has reverse battery protection, drawing negligible current for reverse supply voltages up to 18V.

The input range of the LT1782 includes ground, and a unique feature of this device is its Over-The-Top^™ operation 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-23 packages. For applications requiring higher speed, refer to the LT1783.

Applications

Product Detail

The EVAL-KW4502Z is a demonstration board for evaluating the low-frequency noise of three general operational amplifiers (op amp): (1) low power op amp, (2) low noise, bipolar op amp, and (3) low noise, zero drift op amp.

The EVAL-KW4502Z uses ADA4510-2 which is a dual-channel, 40 V, high precision, low input bias current, low offset voltage, low offset voltage drift, low noise, rail-to-rail input and output operational amplifier that can be used at any point of the signal chain, including sensing, conditioning, and output drive. More importantly, it can operate in low voltage supplies as +/-5V that can be provided by the ADALM2000 Active Learning Module.

The EVAL-KW4502Z accommodates LT1782, ADA4077, and ADA4522 in a thin small outline transistor (TSOT), standard small outline package (SOIC), and mini small outline package (MSOP), respectively.

Full specifications on the LT1782, ADA4077, and ADA4522 are available on the Analog Devices, Inc. website.
