Design by: 8475

This board is an ADC signal-conditioning "shield" for the STM32 nucleo 64 boards. It features a high speed AD8027 rail-to-rail opamp, supplied with ±4.65V from an LM2662 voltage inverter and low noise low drop-out voltage regulators LT1964 and LT1761.

PSU-section:

• 1x LM2662 soic8
  
• 1x LT1964-byp sot23-5
• 1x LT1761-byp sot23-5
• 2x 47uF low ESR (Kemet T520 or equiv.)
• 2x 10uF 1206
• 2x 1uF 0805
• 2x 10nF 0805
• 2x 12k 0805
• 2x 27k 0805

Opamp-section:

• 1x AD8027
• 2x 0.1uF 0805
• 4x resistors for gain and level shift
• 1x 0R for opamp cross-over selection
• 1 u.fl. connector
• 1x 50R 0805
• 1x resistor and 1x cap 0805, for output filter
