| FFF Compatibility | The MAX1681ESA+T shares the identical 8-SOIC footprint and pin assignments (including active-high SHDN on pin 7 and FSEL on pin 1) as the MAX1680ESA+T.Both devices share the standard 8-SOIC package size (3.90mm width, 0.154" body).The electrical parameters are equivalent or superior; the output current is identical at 125mA and input voltage is 2V to 5.5V. The only functional difference is a higher switching frequency range (500kHz/1MHz vs 125kHz/250kHz), which allows for smaller flying capacitors. | The pinout is mostly identical except for Pin 7, which acts as OSC (Oscillator Control) on the MAX660 instead of SHDN (Shutdown) on the MAX1680. If shutdown functionality is not used, it can be a drop-in.Both devices are housed in a standard 8-SOIC (0.154", 3.90mm Width) package.Lacks a dedicated hardware shutdown function (Pin 7 is OSC), and the output current is slightly lower at 100mA compared to 125mA. Additionally, the switching frequency is lower (10kHz/80kHz vs 125kHz/250kHz). | ||
 AI Summary | MAX1680ESA+T by Analog Devices: Charge Pump Switching Regulator IC Positive or Negative Fixed -Vin, 2Vin 1 Output 125mA 8-SOIC (0.154", 3.90mm Width). | The MAX1681ESA+T is a direct, fully pin-compatible sibling of the MAX1680ESA+T in the same product family. It offers the same 125mA current drive in an identical 8-SOIC package, but operates at a higher switching frequency range (500kHz/1MHz).
| The MAX660ESA+T is a similar switched-capacitor charge pump that provides up to 100mA of output current. It is physically compatible but has slight pinout differences (no shutdown pin) and a lower switching frequency.
