... For lower bandwidth applications, the supply current can be reduced with a single external resistor. The LT1210 is available in the TO-220 and DD packages for operation with supplies up to 15V. For 5V applica- tions the device is also available in a low thermal resis- tance SO-16 package. ...

... control the quiescent current in normal operation. The total bias current in the LT1210 is controlled by the current flowing out of the Shutdown pin. When the Shut- down pin is open or driven to the positive supply, the part is shut down ...

... ENABLE Figure 2. Shutdown Interface up the turn-off time and ensures that the LT1210 is completely turned off. Because the pin is referenced to the positive supply, the logic used should have a break- down voltage of greater than the positive supply voltage. No other circuitry is necessary as the internal circuit limits the Shutdown pin current to about 500 A ...

... U When the LT1210 is used to drive capacitive loads, the available output current can limit the overall slew rate. In the fastest configuration, the LT1210 is capable of a slew rate of over 1V/ns. The current required to slew a capacitor at this rate is 1mA per picofarad of capacitance, so 10,000pF would require 10A! The photo (Figure 6) shows ...

... PPLICATI S I FOR ATIO Power Supplies The LT1210 will operate from single or split supplies from 5V (10V total) to 15V (30V total not necessary to use equal value split supplies, however the offset voltage and inverting input bias current will change. The offset voltage changes about 500 V per volt of supply mis- match ...
