www.corebai.com CBM8521-CBM8522-CBM8523-CBM8524 OPERATION INSTRUCTION APPLICATION NOTES The CBM8521, CBM8522, CBM8523, CBM8524 series op amps are unity-gain stable and free from unexpected output phase reversal. They use auto-zeroing techniques to provide low offset voltage and very low drift over time and temperature. Good layout practice mandates use of a 0.1μF capacitor placed closely across the supply pins. For lowest offset voltage and precision performance, circuit layout and mechanical conditions should be optimized. Avoid temperature gradients that create thermoelectric (Seebeck) effects in thermocouple junctions formed from connecting dissimilar conductors. These thermally-generated potentials can be made to cancel by assuring that they are equal on both input terminals.  Use low thermoelectric-coefficient connections (avoid dissimilar metals).  Thermally isolate components from power supplies or other heat-sources.  Shield op amp and input circuitry from air currents, such as cooling fans. Following these guidelines will reduce the likelihood of junctions being at different temperatures, which can cause thermoelectric voltages of 0.1μV/°C or higher, depending on materials used. OPERATING VOLTAGE The CBM8521, CBM8522, CBM8523, CBM8524 series op amps operate over a power-supply range of higher than 7V (absolute maximum) can permanently damage the amplifier. Parameters that vary over supply voltage or temperature are shown in the Typical Characteristics section of this data sheet. CBM8523 ENABLE FUNCTION The enable/shutdown digital input is referenced to the V– supply voltage of the amp. A logic high enables the op amp. A valid logic high is defined as > 75% of the total supply voltage. The valid logic high signal can be up to 5.5V above the negative supply, independent of the positive supply voltage. A valid logic low is defined as < 0.8V above the V– supply pin. If dual or split power supplies are used, be sure that logic input signals are properly referred to the negative supply voltage. The Enable pin must be connected to a valid high or low voltage, or driven, not left open circuit. The logic input is a high-impedance CMOS input, with separate logic inputs provided on the dual version. For battery operated applications, this feature can be used to greatly reduce the average current and extend battery life. The enable time includes one full auto zero cycle required by the amplifier to return to VOS accuracy. Prior to this time, the amplifier functions properly, but with unspecified offset voltage. Disable time is 1μs. When disabled, the output assumes a high-impedance state. This allows the CBM8523 to be operated as a gated amplifier, or to have the output multiplexed onto a common analog output bus. LAYOUT GUIDELINES Attention to good layout practices is always recommended. Keep traces short. When possible, use a PCB ground plane with surface-mount components placed as close to the device pins as possible. Place a 0.1μF capacitor closely across the supply pins. These guidelines should be applied throughout the analog circuit to improve performance and provide benefits such as reducing the EMI (electromagnetic-interference) susceptibility A ll data sheet.com
