Octal 8-bit DAC for automotive signal chains
The MCP48FVB08T-20E/ST: It provides eight independent voltage outputs via an SPI interface, with a typical settling time of 7.8µs. The supply range is 2.7V to 5.5V for both analog and digital rails, and the output is unbuffered with an external voltage reference. The 20-TSSOP package (4.40mm width) suits surface-mount assembly on multi-layer automotive PCBs.
Parametric fit for precision control loops
With eight DAC channels on one die, this part replaces up to eight single-channel DACs or a DAC plus sample-hold bank — saving board area and reducing BOM count in multi-output bias or trim applications. The 8-bit resolution (256 steps) combined with ±0.4 LSB INL and ±0.05 LSB DNL means monotonicity is guaranteed across the full temperature range, critical for closed-loop actuator control where non-monotonic steps cause oscillation. The SPI data interface runs at standard clock rates; the 7.8µs settling time allows each channel to be updated sequentially at roughly 128 kHz aggregate throughput — enough for most sensor bias, VCO tuning, or LED dimming profiles.
