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.
