产品信息
1FEATURES DESCRIPTION
The XTR111 is a precision voltage-to-current 2• EASY-TO-DESIGN INPUT/OUTPUT RANGES:
0mA–20mA, 4mA–20mA, 5mA–25mA AND converter designed for the standard 0mA–20mA or
VOLTAGE OUTPUTS 4mA–20mA analog signals, and can source up to
36mA. The ratio between input voltage and output • NONLINEARITY: 0.002% current is set by the single resistor RSET. The circuit
• LOW OFFSET DRIFT: 1μV/°C can also be modified for voltage output.
• ACCURACY: 0.015%
An external P-MOSFET transistor ensures high
• SINGLE-SUPPLY OPERATION output resistance and a broad compliance voltage
• WIDE SUPPLY RANGE: 7V to 44V range that extends from 2V below the supply voltage,
• OUTPUT ERROR FLAG (EF) VVSP, to voltages well below GND.
• OUTPUT DISABLE (OD) The adjustable 3V to 15V sub-regulator output
• ADJUSTABLE VOLTAGE REGULATOR: provides the supply voltage for additional circuitry.
3V to 15V
The XTR111 is available in MSOP and DFN
surface-mount packages. APPLICATIONS
• UNIVERSAL VOLTAGE-CONTROLLED
CURRENT SOURCE
• CURRENT OR VOLTAGE OUTPUT FOR 3-WIRE
SENSOR SYSTEMS
• PLC OUTPUT PROGRAMMABLE DRIVER
• CURRENT-MODE SENSOR EXCITATION
