12-bit multiplying DAC in a through-hole DIP
The LTC7541AKN#PBF is a 12-bit multiplying digital-to-analog converter from Analog Devices, built on a classic R-2R ladder architecture. It delivers a current output (unbuffered) with a typical settling time of 600 ns, making it suitable for control loops, waveform generation, and precision attenuator applications where update rate matters. The parallel data interface accepts a 12-bit word directly, and the differential output allows the user to configure the output polarity or drive a downstream op-amp for a voltage output. The part operates from a single analog and digital supply rail spanning 5 V to 16 V, which simplifies power distribution on the board.
The ±0.5 LSB maximum INL and DNL (both at ±0.5 LSB max) means the output code is within half a least-significant bit of the ideal transfer function across all codes. No missing codes at 12-bit resolution. The 600 ns typical settling time to ±0.5 LSB defines the maximum update rate. The external reference input lets you set the full-scale output range independently of the supply rails.
Package and temperature grade — fit for the board
The 18-pin DIP (0.300" body width, 7.62 mm pitch) is a through-hole package, so this part is a natural fit for prototyping boards, legacy designs, or any build where wave soldering is preferred over reflow. The ROHS3 compliance means no lead in the solder finish, which is the current standard for most production runs.
