Package: SSOP-28_5.3x10.2mm_P0.65mm Library: Package_SO Category: IC Package Pads: 28 Pitch: 0.65mm Body Size: 5.3 x 10.2mm Mounting: Surface Mount

Description

The SSOP-28 is a 28-pin shrink small outline package with 0.65mm pitch and a 5.3 x 10.2mm body. It provides high pin count in a narrow form factor, making it ideal for ICs that need many I/O lines without the bulk of a QFP. Classic inhabitants include the FTDI FT232R USB-UART bridge, MCP23017 I/O expander, ADS1256 precision ADC, and various motor driver ICs. The 0.65mm pitch is still manageable with careful hand soldering and a drag-soldering technique.

Usage Notes

  • Designed for reflow soldering (paste stencil recommended)
  • Pad size optimized for 0.65mm pitch components
  • Follow IPC-7351 land pattern guidelines
