16-bit ∆Σ A/D converter IC with programmable gain instrumentation amplifier
Overview
The RAA730101 is a 16-bit ΔΣ A/D converter IC with a programmable gain instrumentation amplifier ideal for
differential output sensors used for measuring flow and pressure. The RAA730101 incorporates a temperature sensor, a
power supply for external sensor, and an internal reference voltage generator. Using Serial Peripheral Interface (SPI)
communication or Universal Asynchronous Receiver Transmitter (UART) communication, the RAA730101 controls
system configurations for each function block from an external device and outputs measured data to the external device.
The RAA730101 also incorporates flash memory for storing system configurations for each function block. The
RAA730101 uses a 36-pin FBGA package, which enables a more compact set design for measuring flow and pressure.
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.
Applications
• Industrial equipment for measuring items such as pressure, flow, and temperature
• Healthcare equipment for measuring items such as blood pressure and weight
