This device offers 4 MHz of gain-bandwidth product, 13-V/µs slew rate, and fast settling time, without the use of JFET device technology. Although the TL3472 can be operated from split supplies, it is particularly suited for single-supply operation because the common-mode input voltage range includes ground potential (VCC–). With a Darlington transistor input stage, this device exhibits high input resistance, low input offset voltage, and high gain. The all-npn output stage, characterized by no dead-band crossover distortion and large output voltage swing, provides high-capacitance drive capability, excellent phase and gain margins, low open-loop high-frequency output impedance, and symmetrical source/sink ac frequency response. This low-cost amplifier is an alternative to the MC33072 and the MC34072 operational amplifiers. The TL3472C is characterized for operation from 0°C to 70°C. The TL3472I is characterized for operation from –40°C to 105°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–. 2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive input current can flow when the input is less than VCC– – 0.3 V. 3. The output can be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum dissipation rating is not exceeded. 4. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 5. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions 2 VCC± Supply voltage VIC Common mode input voltage Common-mode TA Operating free-air free air temperature VCC = 5 V VCC± = ±15 V TL3472C TL3472I POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 MIN MAX 4 36 0 2.8 –15 12.8 0 70 –40 105 UNIT V V °C TL3472 HIGH-SLEW-RATE, SINGLE-SUPPLY OPERATIONAL AMPLIFIER SLOS200E – OCTOBER 1997 – REVISED FEBRUARY 2000 electrical characteristics at specified free-air temperature, VCC± = ±15 V (unless otherwise noted) PARAMETER TEST CONDITIONS TA 25°C VCC = 5 V VIO aV IO Input offset voltage Temperature coefficient of input offset voltage IIO Input offset current IIB Input bias current VICR VOH Common-mode input voltage range High-level output voltage 25°C VCC = ±15 V VIC = 0, VO = 0, RS = 50 Ω VCC = ±15 V VCC = ±15 V Low-level output voltage VCC+ = 5 V, RL = 10 kΩ VCC– = 0, Large-signal g g differential voltage amplification IOS Short circuit output current Short-circuit CMRR 10 10 25°C 6 100 –15 to 12.8 Full range‡ –15 to 12.8 25°C 3.7 4 25°C 13.6 14 Full range‡ 13.4 RL = 2 kΩ 0.1 0.3 –14.3 25 Full range‡ 20 VO = 0 VO = 0 25°C Common mode rejection ratio Common-mode VIC = VICR(min) (min), RS = 50 Ω kSVR Supply-voltage rejection ratio (∆VCC±/∆VIO) VCC± = ±13.5 V to ±16.5 V, ICC Supply current (per channel) 100 V/mV –10 –34 20 27 25°C 65 97 dB 25°C 70 97 dB mA 25°C Full range‡ 3.5 4.5 4.5 5.5 25°C 3.5 4.5 VCC+ = 5 V, VO = 2.5 V, VCC– = 0, No load V –13.5 25°C Sink: VID = –1 V, µA V –14.7 Source: VID = 1 V, nA V 25°C RL = 2 kΩ No load 500 25°C Full range‡ RS = 100 Ω 75 700 25°C RL = 2 kΩ mV µV/°C 300 Full range‡ VO = ±10 V, V VO = 0 0, 10 1.0 Full range‡ 25°C RL = 2 kΩ AVD 1.5 UNIT 12 RS = 50 Ω VCC– = 0, MAX Full range‡ VCC = ±15 V VCC+ = 5 V, RL = 10 kΩ TYP† Full range‡ RL = 2 kΩ VOL MIN mA † All typical values are at TA = 25°C. ‡ Full range is 0°C to 70°C for the TL3472C device and –40°C to 105°C for the TL3472I device.
