9-5; Rev ; / +V/+5V, 5MHz, SOT ADC Buffer Amplifiers General Description The MAX85/MAX86 single and MAX87/MAX88/ MAX87/MAX88 dual ADC buffer amplifiers feature high-speed performance and single +V supply operation. The MAX85/MAX86/MAX88 and MAX88 offer a disable feature that reduces power-supply current and places the outputs in a high-impedance state. All six devices operate from a +.85V to +6.5V single supply or from ±.5V to ±.5V dual supplies. The commonmode input voltage range extends to the negative powersupply rail (ground in single-supply applicatio). These devices require ma of quiescent supply current per amplifier while achieving a 5MHz -db bandwidth and a 5V/µs slew rate. The combination of an 8 (to.%) settling time, 88dBc (f = 5MHz) of SFDR, and up to ma output drive makes these amplifiers ideal for highspeed ADC drivers for communicatio and itrumentation applicatio. In addition, when disabled, their high output impedance makes them ideal for multiplexing applicatio. The MAX85/MAX86 are available in space-saving 6-pin SOT and 8-pin SO packages. The MAX87/ MAX87 come in 8-pin µmax and 8-pin SO packages, while the MAX88/MAX88 come in -pin µmax and -pin SO packages.

They operate from a single +.85V to +6.5V supply or dual ±.5V to ±.5V supplies. Their high output drive, wide bandwidth, fast settling, low noise, and low distortion make them ideal for the brutal task of meeting the dynamic input drive requirements of high-speed ADCs or other demanding applicatio. The MAX85/MAX86/MAX88 and MAX88 have a high-speed disable mode that places the outputs in a high-impedance state and lowers operating supply current to ma. The enable time is typically, and the disable time is typically 5. The MAX85/MAX86 have a single enable pin (DISABLE), and the MAX88/ NAME Pin Description Amplifier B Noninverting Input Amplifier B Inverting Input Amplifier B Output FUNCTION Not Internally Connected.

The MAX85/MAX87/MAX88 are internally compeated for unity-gain stability. The MAX86/ MAX87/MAX88 are compeated for gai of +5V/V or greater. Applicatio Information Inverting and Noninverting Configuratio Select the gain-setting feedback (R F ) and input (R G ) resistor values coidering the following criteria: large resistor values increase voltage noise and interact with the amplifier s input and PC board capacitance to effect system bandwidth. This generates undesirable poles and zeros that decrease bandwidth or cause oscillatio.
+V/+5V, 5MHz, SOT ADC Buffer Amplifiers For example, a noninverting gain-of-two configuration (R F = R G ) using kω resistors, combined with pf typical amplifier input capacitance, generates a pole at 59MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing these kω resistors to Ω extends the pole frequency to.59ghz, but affects output swing by adding Ω in parallel with the amplifier s load resistor. The typical value for R F is Ω. Layout and Power-Supply Bypassing These amplifiers operate from a single +.85V to +6.5V power supply or from ±.5V to ±.5V dual supplies. For single-supply operation, bypass V CC to ground with a.nf capacitor as close to the pin as possible, with a.µf capacitor in parallel. If operating with dual supplies, bypass each supply with capacitors to ground. Observe the following guidelines: A solid ground plane is essential for good high-frequency behavior. Where possible, use multiple ground vias. Use a PC board with at least two layers. Avoid areas of unreferenced copper-clad. Keep signal traces as short and as straight as possible. Do not make sharp tur; round all trace corners. Use a cotant-impedance board design if possible. High-Speed Disable The MAX85/MAX86/MAX88 and MAX88 feature a disable (DISABLE_) input that places the amplifier in a low-power, high-output-impedance state. When DISABLE_ is asserted, the amplifier s output impedance is typically 5kΩ. This high output impedance, combined with the low pf output capacitance, make these devices ideal for ADC input multiplexing applicatio or switch applicatio. Typical enable/disable times are /5. Output Capacitive Loading and Stability These op amps are optimized for AC performance. They are not designed to drive highly reactive loads, which decrease phase margin and may produce excessive ringing and oscillation. A small isolation resistor (usually Ω to Ω) placed before the reactive load reduces possible ringing and oscillation (Figure ). At higher capacitive loads, AC performance is dependent on the interaction of the load capacitance, the isolation resistor, and on-board layout. Output Drive Capability The MAX85 MAX88 and MAX87/MAX88 have an output sink capability of 6mA and a source capability of 77mA. This high current ability allows them to drive low-impedance and dynamic-impedance ADC inputs. The linear output range of these devices is (V EE +.V) to (V CC -.V). Operation beyond this range is not recommended due to reduced gain and phase margin. R G R F MAX85 MAX86 MAX87 MAX88 MAX87 MAX88 Figure.
