Quad current-controlled amplifier in a 16-pin DIP
The Analog Devices SSM2024P is a quad current-controlled amplifier — four independent amplifier channels whose gain is set by a control current rather than external resistors, packaged in a 16-lead PDIP (0.300" body width) for through-hole mounting. Target applications listed on the datasheet cover automatic gain control (AGC) loops and voltage-controlled oscillator (VCO) stages, where the ability to vary gain with a DC current simplifies level-control circuitry.
RoHS non-compliance — plan for exemption or alternative
This part is RoHS non-compliant (leaded solder terminations), which rules it out for any build requiring RoHS-10 conformity unless a specific exemption applies. Factor in the exemption paperwork or a Pb-free alternative if your BOM is RoHS-mandated.
Through-hole DIP — legacy footprint, rework-friendly
The 16-DIP package (7.62 mm row spacing) is a through-hole form factor that requires drilled plated-through holes on the PCB — no SMT reflow. DIPs are straightforward to hand-solder and rework, but they consume more board area and are incompatible with high-density SMT assembly lines without a wave-solder step.
