It integrates one ADC and one DAC with a serial data interface, purpose-built for generating and processing ringing tones in telecom line cards and subscriber-line interface circuits. Operating from a single 5V rail — both analog and digital supplies share the 4.75V to 5.25V range — which keeps the power tree simple: one 5V regulator feeds the whole device. ## Temperature range and package fit Rated for -25°C to 80°C, this part suits outdoor telecom cabinets and factory-floor PBX equipment where the ambient stays above freezing but does not reach the full industrial 85°C ceiling. The 28-SOIC (7.50 mm width) body in P-DSO-28 footprint is a standard surface-mount package — no exotic reflow profile needed. ## Active production — no obsolescence watch Infineon lists the PSB2161TV1.1 as Active.","metaTitle":"PSB2161TV1.1 Audio Ringing Codec – Infineon, Active, 28-SOIC","metaDescription":"Infineon PSB2161TV1.1 ARCOFI-SP audio ringing codec.
