Each amplifier features 200 uA typical supply current, 1 MHz gain-bandwidth product, and 3.5 V\/us slew rate. The JFET input stage provides extremely high input impedance (10^12 Ohm), low input bias current (30 pA typical), and a common-mode input voltage range that includes the positive supply rail. With internal frequency compensation, output short-circuit protection, and EMI filtering, the TL064CDR is the low-power variant of the industry-standard TL074 and TL084 families.","working_principle":"The TL064CDR uses a JFET-input differential pair as the first gain stage, which provides very high input impedance and very low input bias current compared to bipolar-input op-amps. The differential input stage amplifies the voltage difference between the inverting and non-inverting inputs, converting it to a single-ended signal. A high-gain voltage amplifier stage further amplifies this signal, and a class-AB output buffer provides low-impedance output drive capability with short-circuit protection. Internal frequency compensation (a dominant pole capacitor) ensures stability in unity-gain configurations without external components. The JFET input allows the common-mode input voltage to extend to the positive supply rail, enabling single-supply operation in many applications. The trade-off for the low 200 uA per-amplifier quiescent current (compared to 1.4 mA for the TL074) is a slightly lower gain-bandwidth product (1 MHz versus 3 MHz) and slower slew rate (3.5 V\/us versus 13 V\/us). The integrated EMI filter on the input pins rejects high-frequency interference, improving robustness in electrically noisy environments.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>1OUT<\/td><td>Amplifier 1 output<\/td><\/tr><tr><td>2<\/td><td>1IN-<\/td><td>Amplifier 1 inverting input<\/td><\/tr><tr><td>3<\/td><td>1IN+<\/td><td>Amplifier 1 non-inverting input<\/td><\/tr><tr><td>4<\/td><td>VCC+<\/td><td>Positive supply voltage (up to 18 V)<\/td><\/tr><tr><td>5<\/td><td>2IN+<\/td><td>Amplifier 2 non-inverting input<\/td><\/tr><tr><td>6<\/td><td>2IN-<\/td><td>Amplifier 2 inverting input<\/td><\/tr><tr><td>7<\/td><td>2OUT<\/td><td>Amplifier 2 output<\/td><\/tr><tr><td>8<\/td><td>3OUT<\/td><td>Amplifier 3 output<\/td><\/tr><tr><td>9<\/td><td>3IN-<\/td><td>Amplifier 3 inverting input<\/td><\/tr><tr><td>10<\/td><td>3IN+<\/td><td>Amplifier 3 non-inverting input<\/td><\/tr><tr><td>11<\/td><td>VCC-<\/td><td>Negative supply voltage (down to -18 V)<\/td><\/tr><tr><td>12<\/td><td>4IN+<\/td><td>Amplifier 4 non-inverting input<\/td><\/tr><tr><td>13<\/td><td>4IN-<\/td><td>Amplifier 4 inverting input<\/td><\/tr><tr><td>14<\/td><td>4OUT<\/td><td>Amplifier 4 output<\/td><\/tr><\/table>\n<p>TL064CDR uses the SOIC-14 (D) surface-mount package with standard quad op-amp pinout: Pin 1 = Output 1, Pin 2 = Inverting Input 1 (-), Pin 3 = Non-inverting Input 1 (+), Pin 4 = VCC+, Pin 5 = Non-inverting Input 2 (+), Pin 6 = Inverting Input 2 (-), Pin 7 = Output 2, Pin 8 = Output 3, Pin 9 = Inverting Input 3 (-), Pin 10 = Non-inverting Input 3 (+), Pin 11 = VCC-, Pin 12 = Non-inverting Input 4 (+), Pin 13 = Inverting Input 4 (-), Pin 14 = Output 4.
