Despite being low power, these amplifiers provide excellent overall performance. They offer a high bandwidth of 105 MHz at a gain of +1, a high slew rate of 160 V/µs, and a low input offset voltage of 125 µV (maximum). A shutdown pin allows further reduction of the quiescent supply current to 2.9 µA. For power sensitive applications, the shutdown mode offers a very fast turn-on time of 3 µs. This allows the user to dynamically manage the power of the amplifier by turning the amplifier off between ADC samples.

Driving the AD7980 with the ADA4805-1/ADA4805-2 The Analog Devices, Inc., proprietary extra fast complementary bipolar (XFCB) process allows both low voltage and low current noise (5.9 nV/√Hz, 0.6 pA/√Hz). The ADA4805-1/ADA4805-2 operate over a wide range of supply voltages from ±1.5 V to ±5 V, as well as single 3 V and 5 V supplies, making them ideal for high speed, low power instruments. The ADA4805-1 is available in a 6-lead SOT-23 and a 6-lead SC70 package. The ADA4805-2 is available in an 8-lead MSOP and a 10-lead LFCSP package. These amplifiers are rated to work over the industrial temperature range of −40°C to +125°C. 0 8020 40 60 70503010 FREQUENCY (kHz) –20 0 –40 –60 –80 –100 A M PL IT U D E (d B ) –120 –140 –160 –180 11 34 5- 10 2 INPUT FREQUENCY = 10kHz SNR = 89.4dB THD = 104dB SINAD = 89.3dB Figure 2.

This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. THERMAL RESISTANCE θJA is specified for the worst case conditions, that is, θJA is specified for a device soldered in a circuit board for surface-mount packages. Table 6 lists the θJA for the ADA4805-1/ADA4805-2. Table 6. Thermal Resistance Package Type θJA Unit 6-Lead SC70 223.6 °C/W 6-Lead SOT-23 209.1 °C/W 8-Lead MSOP 123.8 °C/W 10-Lead LFCSP 51.4 °C/W MAXIMUM POWER DISSIPATION The maximum safe power dissipation for the ADA4805-1/ ADA4805-2 is limited by the associated rise in junction temperature (TJ) on the die. At approximately 150C, which is the glass transition temperature, the properties of the plastic change. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the ADA4805-1/ADA4805-2. Exceeding a junction temperature of 175C for an extended period of time can result in changes in silicon devices, potentially causing degradation or loss of functionality. The power dissipated in the package (PD) is the sum of the quiescent power dissipation and the power dissipated in the die due to the ADA4805-1/ADA4805-2 output load drive. The quiescent power dissipation is the voltage between the supply pins (VS) multiplied by the quiescent current (IS). PD = Quiescent Power + (Total Drive Power − Load Power)   L OUT L OUTS SSD R V R VV IVP 2 2        RMS output voltages must be considered. If RL is referenced to −VS, as in single-supply operation, the total drive power is VS × IOUT. If the rms signal levels are indeterminate, consider the worst case, when VOUT = VS/4 for RL to midsupply.     L S SSD R V IVP 24/  In single-supply operation with RL referenced to −VS, worst case is VOUT = VS/2. Airflow increases heat dissipation, effectively reducing θJA. Also, more metal directly in contact with the package leads and exposed pad from metal traces, through holes, ground, and power planes reduces θJA. Figure 3 shows the maximum safe power dissipation in the package vs. the ambient temperature on a JEDEC standard, 4-layer board. θJA values are approximations.
