description (continued)
The THS5641A 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 THS5641A 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.
