Industrial Control & Low Voltage Instrumentation Application

Using the FSA1256 and FSA1258 Dual SPST Low Ohm Analog Switches.

Key Switch Specifications:

• On resistance (R_ON): typically 0.95 ohm at 4.5V V_CC and 2.6 ohm at 2.7V power supply
  
• 1.65 to 5.5V voltage operational range.
• Leakage current: 2nA maximum under 25ºC

Advantages:

• Low Voltage Data Acquisition for industrial control and portable instrumentation.
• Low On resistance and low leakage current, important to minimize the sampled data error from switch offset voltage.
• Low charge injection enhances the accuracy of SAMPLE/HOLD circuitry.
• Small package (MicroPak™: only 2.56mm²)
  

Using the FSA1156 and FSA1157 SPST Low Ohm Analog Switches

Key Switch Specifications:

• On resistance (R_ON): typically 0.75 ohm at 4.5V VCC and 1.4 ohm at 2.7V power supply
• 1.65 to 5.5V operational
• Leakage current: 700pA typical
• ESD: 8KV (HBM)

Advantages:

• Low Voltage Data Acquisition
• Low On resistance and low leakage current (700pA typical and 4nA maximum), which is important to minimize the sampled data error from switch offset voltage.
• low charge injection also enhance the accuracy of SAMPLE/HOLD circuitry.
• Smallest package in industry (MicroPak™: only1.45mm²)
