The TLC2801 combines the noise performance of the lowest-noise JFET amplifiers with the dc precision available previously only in bipolar amplifiers. The Advanced LinCMOS process uses silicon-gate technology to obtain input offset voltage stability with temperature and time that far exceeds that obtainable using metal-gate technology. In addition, this technology makes possible input impedance levels that meet or exceed levels offered by top-gate JFET and expensive dielectric-isolated devices. The device inputs and output are designed to withstand – 100-mA surge currents without sustaining latch-up. In addition, internal ESDprotection circuits prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in degradation of the device parametric performance. 1 8 2 7 3 6 4 5 NC VDD + OUT NC NC – No internal connection LARGE-SIGNAL DIFFERENTIAL VOLTAGE AMPLIFICATION vs FREE-AIR TEMPERATURE 130 AVD AVD– Large-Signal Differential Voltage Amplification – dB The combination of excellent dc and noise performance with a common-mode input voltage range that includes the negative rail makes the TLC2801 an ideal choice for high-impedance, low-level signal conditioning applications in either single-supply or split-supply configurations.

Not only does this measurement require a picoammeter, but test socket leakages can easily exceed the actual device bias currents. To measure these small currents, Texas Instruments uses a two-step process. The socket leakage is measured using picoammeters with bias voltage applied but with no device in the socket. The device is then inserted in the socket and a second test measuring both the socket leakage and the device input bias current is performed. The two measurements are then subtracted algebraically to determine the bias current of the device. 3–8 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC2801Z, TLC2801Y Advanced LinCMOS LOW-NOISE PRECISION OPERATIONAL AMPLIFIERS SLOS116B – JULY 1982 – REVISED SEPTEMBER 1996 TYPICAL CHARACTERISTICS Table of Graphs FIGURE IIB VOM Input bias current vs Free-air temperature 5 Maximum peak output voltage vs Free-air temperature 6 VOH VOL High-level output voltage vs Free-air temperature 7 Low-level output voltage vs Free-air temperature 8 AVD IOS Differential voltage amplification vs Free-air temperature 9 Short-circuit output current vs Free-air temperature 10 IDD SR Supply current vs Free-air temperature 11 Slew rate vs Free-air temperature 12 Gain-bandwidth product vs Free-air temperature 13 INPUT BIAS CURRENT vs FREE-AIR TEMPERATURE MAXIMUM PEAK OUTPUT VOLTAGE vs FREE-AIR TEMPERATURE 300 VOM VOM – Maximum Peak Output Voltage – V IIIB IB – Input Bias Current – pA 250 6 VDD ± = ± 5 V VO = 0 VIC = 0 200 150 100 50 0 – 50 – 25 0 25 50 75 100 125 TA – Free-Air Temperature – °C 150 4 2 VDD ± = ± 5 V RL = 10 kΩ 0 –2 –4 –6 – 50 – 25 Figure 5 0 25 50 75 100 125 TA – Free-Air Temperature – °C 150 Figure 6 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3–9 TLC2801Z, TLC2801Y Advanced LinCMOS LOW-NOISE PRECISION OPERATIONAL AMPLIFIERS SLOS116B – JULY 1982 – REVISED SEPTEMBER 1996 TYPICAL CHARACTERISTICS HIGH-LEVEL OUTPUT VOLTAGE vs FREE-AIR TEMPERATURE 1.5 VDD = 5 V RL = 10 kΩ VDD = 5 V VOL VOL – Low-Level Output Voltage – V VV0H OH – High-Level Output Voltage – V 6 LOW-LEVEL OUTPUT VOLTAGE vs FREE-AIR TEMPERATURE 5 4 3 2 1 0 – 50 – 25 0 25 50 75 100 125 TA – Free-Air Temperature – °C IOL = 5 mA 1 0.5 IOL = 1 mA 0 – 50 150 – 25 0 25 50 75 100 125 TA – Free-Air Temperature – °C Figure 8 Figure 7 LARGE-SIGNAL DIFFERENTIAL VOLTAGE AMPLIFICATION vs FREE-AIR TEMPERATURE SHORT-CIRCUIT OUTPUT CURRENT vs FREE-AIR TEMPERATURE 15 120 VDD ± = ± 5 V, RL = 500 kΩ 110 VDD ± = ± 5 V, RL = 10 kΩ 100 90 80 – 50 – 25 0 25 50 75 100 125 150 IIOS OS – Short-Circuit Output Current – mA AVD AVD– Large-Signal Differential Voltage Amplification – dB 130 ÁÁ ÁÁ ÁÁ VDD ± = ± 5 V VO = 0 10 5 VID = – 100 mV 0 –5 VID = 100 mV – 10 – 15 – 50 – 25 0 25 50 Figure 10 Figure 9 POST OFFICE BOX 655303 75 100 TA – Free-Air Temperature – °C TA – Free-Air Temperature – °C 3–10 150 • DALLAS, TEXAS 75265 125 150 TLC2801Z, TLC2801Y Advanced LinCMOS LOW-NOISE PRECISION OPERATIONAL AMPLIFIERS SLOS116B – JULY 1982 – REVISED SEPTEMBER 1996 TYPICAL CHARACTERISTICS SLEW RATE vs FREE-AIR TEMPERATURE SUPPLY CURRENT vs FREE-AIR TEMPERATURE 4 1.2 VDD ± = ± 5 V SR– 0.8 SR – Slew Rate – V/ V/us µs 3 VDD = 5 V 0.6 0.4 SR+ 2 1 VDD ± = ± 5 V RL = 10 kΩ CL = 100 pF 0.2 VO = VDD +/2 No Load 0 – 50 – 25 0 25 50 75 100 TA – Free-Air Temperature – °C 125 0 – 50 150 0 – 25 25 50 75 100 125 150 TA – Free-Air Temperature – °C Figure 12 Figure 11 GAIN-BANDWIDTH PRODUCT vs FREE-AIR TEMPERATURE 2.5 RL = 10 kΩ CL = 100 pF Gain-Bandwidth Product – MHz IIDD DD – Supply Current – mA 1.0 VDD ± = ± 5 V 2 VDD = 5 V 1.5 1 – 50 – 25 0 25 50 75 100 TA – Free-Air Temperature – °C 125 150 Figure 13 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3–11 TLC2801Z, TLC2801Y Advanced LinCMOS LOW-NOISE PRECISION OPERATIONAL AMPLIFIERS SLOS116B – JULY 1982 – REVISED SEPTEMBER 1996 3–12 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 IMPORTANT NOTICE Texas Instruments and its subsidiaries (TI) reserve the right to make changes to their products or to discontinue any product or service without notice, and advise customers to obtain the latest version of relevant information to verify, before placing orders, that information being relied on is current and complete.
