TS274 High performance CMOS quad operational amplifier Features ■ Output voltage can swing to ground ■ Excellent phase margin on capacitive loads ■ Gain bandwidth product: 3.5 MHz ■ Unity gain stable ■ Two input offset voltage selections DIP14 (Plastic package) 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. These series are ideally suited for low consumption applications. TSSOP14 (Thin shrink small outline package) Three power consumptions are available thus offering the best consumption-speed ratio for your application: ■ ICC = 10 µA/amp: TS27L4 (very low power) ■ ICC = 150 µA/amp: TS27M4 (low power) ■ ICC = 1 mA/amp: TS274 (standard) Pin connections (top view) - - 13 Inverting Input 4 + + 12 Non-inverting Input 4 11 VCC - Non-inverting Input 2 5 + + 10 Non-inverting Input 3 Inverting Input 2 6 - - 9 Inverting Input 3 8 Output 3 Output 2 7 For enhanced features of TS274, in particular railto-rail capability and low offset voltage, two new Part number Inverting Input 1 2 Non-inverting Input 1 3 VCC + 4 These CMOS amplifiers offer very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input currents drift with temperature (see Figure 5 on page 6).

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 1.5kΩ 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 < 5Ω). 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.

Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way. 4.2 Macromodel code ******************************** .SUBCKT TS27X 1 2 3 4 5 *** INP- = 1, INP+ =2, OUT = 3 VDD=4 VSS = 5 *** TYPE = TS271/TS272/TS274 .MODEL MDTH D IS=1E-8 KF=2.664E-16 CJO=10F ***INPUT STAGE CIP 2 5 1E-12 CIN 1 5 1E-12 EIP 10 5 2 5 1 EIN 16 5 1 5 1 RIP 10 11 8 RIN 15 16 8 RIS 11 15 223.84 CPS 11 15 1E-9 DIP 11 120 MDTH 400E-12 DIN 15 140 MDTH 400E-12 RDEG1 12 120 4400 RDEG2 14 140 4400 VOFP 12 13 DC 0 VOFN 13 14 DC 0 IPOL 13 5 38E-6 ***ICC DICC1 4 31 MDTH 400E-12 DICC2 31 32 MDTH 400E-12 DICC3 32 33 MDTH 400E-12 DICC4 33 34 MDTH 400E-12 RICC 34 5 20E3 ICC 4 5 600E-6 ***COMMON MODE INPUT LIMITATION DINN 17 13 MDTH 400E-12 VIN 17 5 DC -0.1 8/14 TS274 Macromodel DINR 15 18 MDTH 400E-12 VIP 4 18 DC 2.2 ***GM1 STAGE FGM1P 119 5 VOFP 1 FGM1N 119 5 VOFN 1 RAP 119 4 1E6 RAN 119 5 1E6 ***GM2 STAGE G2P 19 5 119 5 4E-4 G2N 19 5 119 4 4E-4 R2P 19 4 450E3 R2N 19 5 450E3 ***COMPENSATION CC 19 119 7p ***BUFFER EBUF 20 5 19 5 1 ***SHORT-CIRCUIT LIMITATIONS( ISINK, ISOURCE) DOPM 19 22 MDTH 400E-12 DONM 21 19 MDTH 400E-12 HOPM 22 28 VOUT 910 VIPM 28 4 DC 50 HONM 21 27 VOUT 1222 VINM 5 27 DC 50 VOUT 3 23 DC 0 ***VOH, VOL DEFINITIONS DOP 19 25 MDTH 400E-12 VOP 4 25 2.5 DON 24 19 MDTH 400E-12 VON 24 5 0.92 ***OUTPUT RESISTOR ROUT 23 20 10 .ENDS 9/14 Package information 5 TS274 Package information In order to meet environmental requirements, ST offers these devices in ECOPACK® packages.
