TS274CDT STMicroelectronics

TS274 High performance CMOS quad operational amplifier Features Output voltage can swing to ground Excellent phase margin on capacitive loads DIP14 Gain bandwidth product: 3.5 MHz (Plastic package) Unity gain stable Two input offset voltage selections Description SO-14 (Plastic micropackage) The TS274 devices are low cost, quad operational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process giving an excellent consumption-speed ratio. TSSOP14 These series are ideally suited for low (Thin shrink small outline package) consumption applications. Three power consumptions are available thus Pin connections (top view) offering the best consumption-speed ratio for your application: Output 1 1 14 Output 4 I = 10 A/amp: TS27L4 (very low power) CC Inverting Input 1 2 13 Inverting Input 4 - - I = 150 A/amp: TS27M4 (low power) CC + + Non-inverting Input 1 3 12 Non-inverting Input 4 I = 1 mA/amp: TS274 (standard) CC + - V 4 11 V CC CC These CMOS amplifiers offer very high input Non-inverting Input 2 5 10 Non-inverting Input 3 + + impedance and extremely low input currents.

For enhanced features of TS274, in particular rail- families, TSV91x and TSV99x will better suit low to-rail capability and low offset voltage, two new voltage applications. Table 1.

All values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage. 4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 3.
