description (continued)
The THS5641 provides a nominal full-scale differential output current of 20 mA and >300 k
output impedance,
supporting both single-ended and differential applications. The output current can be directly fed to the load
(e.g., external resistor load or transformer), with no additional external output buffer required. An accurate
on-chip reference and control amplifier allows the user to adjust this output current from 20 mA down to 2 mA,
with no significant degradation of performance. This reduces power consumption and provides 20 dB gain range
control capabilities. Alternatively, an external reference voltage and control amplifier may be applied in
applications using a multiplying DAC.
The THS5641 is available in both a 28-pin SOIC and TSSOP package. The device is characterized for operation
over the industrial temperature range of –40
°C to 85°C.
