Features

 16-bit ΔΣ A/D converter

 Programmable gain instrumentation amplifier (capable of gain adjustment from x1 to x32 and adjustment of offset

voltage)

 Four analog input channels (differential input mode or single-ended input mode can be specified for each input

channel)

 Temperature sensor (internally connected to 16-bit ΔΣ A/D converter)

 Power supply for external sensor (output voltage: 1.2 to 2.2 V)

 Internal system clock (OSC) oscillator (clock frequency: 20 MHz (Typ.))

 Power-on reset (POR) circuit

 Serial interface (SPI or UART communication is selectable)

 256-byte flash memory for storing system configuration data

 Operating voltage range: 2.7 V ≤ VDD ≤ 5.5 V

 Operating temperature range:

 125C models: 40C ≤ TA ≤ 125C (during normal operation)

105C models: 40C ≤ TA ≤ 105C (during normal operation)

 125C and 105C models: 10C ≤ TA ≤ 85C (during flash memory programming)

 Package: 36-pin plastic FBGA (4 mm  4 mm, 0.5-mm pitch)

Caution Flash memory programming refers to erasing or writing of data in the flash memory.
