In inverting mode, it generates a negative supply from a positive input, while in doubling mode it can produce up to 14 V from a 7 V input. The SOIC-8 package includes a frequency control (FC) pin to select between 25 kHz for low-noise operation and 120 kHz for smaller capacitor size, requiring only 10 uF or 2.2 uF external capacitors respectively.","working_principle":"The ADM660ARZ-REEL7 operates as a switched-capacitor charge pump using a two-phase clock. During Phase 1, an internal MOSFET switch connects the flying capacitor (C1) between VIN and ground, charging it to the input voltage. During Phase 2, the switch reconnects C1 between ground and the output, transferring its charge to the output capacitor (C2). In inverter mode, the output capacitor is connected with opposite polarity, generating a negative voltage equal to -VIN. In doubler mode, the flying capacitor is stacked on top of the input voltage, producing approximately 2 x VIN at the output. The FC pin selects the internal oscillator frequency: 25 kHz (FC low or open) or 120 kHz (FC connected to LV), allowing trade-off between capacitor size and output ripple. The LV (Low Voltage) pin enables operation down to 1.5 V input.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>LV<\/td><td>Low voltage enable; connect to GND for VIN below 3 V, leave open for VIN above 3 V<\/td><\/tr><tr><td>2<\/td><td>OSC<\/td><td>Oscillator input; connect external capacitor to reduce frequency or drive with external clock<\/td><\/tr><tr><td>3<\/td><td>VOUT<\/td><td>Negative output voltage (inverter mode) or doubled output (doubler mode)<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground reference<\/td><\/tr><tr><td>5<\/td><td>CAP+<\/td><td>Positive terminal of flying capacitor C1<\/td><\/tr><tr><td>6<\/td><td>CAP-<\/td><td>Negative terminal of flying capacitor C1<\/td><\/tr><tr><td>7<\/td><td>OSC2<\/td><td>Oscillator output (internal clock); leave open for normal operation<\/td><\/tr><tr><td>8<\/td><td>VIN<\/td><td>Positive supply input (+1.5 V to +7 V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>Negative Rail Generation<\/strong>: Creating -5 V or -12 V from a positive supply for op-amp biasing in single-supply systems<\/li><li><strong>Display LCD Bias<\/strong>: Inverting supply for contrast adjustment in LCD modules<\/li><li><strong>Portable Instrumentation<\/strong>: Dual-rail analog front-end supply from a single battery<\/li><li><strong>RS-232 Transceivers<\/strong>: Generating the negative supply required by RS-232 line drivers<\/li><li><strong>Voltage Doubling<\/strong>: Boosting 3.3 V or 5 V logic rails to 6.6 V or 10 V for gate drive<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>VIN<\/th><th>Iout<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>ICL7660<\/td><td>Renesas<\/td><td>1.5-10 V<\/td><td>20 mA<\/td><td>SOIC-8<\/td><td>Lower cost, lower current<\/td><\/tr><tr><td>MAX660<\/td><td>Maxim<\/td><td>1.5-5.5 V<\/td><td>100 mA<\/td><td>SOIC-8<\/td><td>Pin-compatible, higher freq<\/td><\/tr><tr><td>LM2662<\/td><td>Texas Instruments<\/td><td>1.5-5.5 V<\/td><td>200 mA<\/td><td>SOIC-8<\/td><td>Higher output current<\/td><\/tr><tr><td>ADM8660<\/td><td>Analog Devices<\/td><td>1.5-7 V<\/td><td>100 mA<\/td><td>SOIC-8<\/td><td>Shutdown feature added<\/td><\/tr><tr><td>TPS60400<\/td><td>Texas Instruments<\/td><td>1.6-5.5 V<\/td><td>60 mA<\/td><td>SOT-23<\/td><td>Ultra-small package<\/td><\/tr><\/table>\n<p>ADM660ARZ-REEL7 is a CMOS charge pump from ADI in SOIC-8.
