Eight channels, 10 bits, one small package
The TLV5631IPW packs eight 10-bit DACs with voltage-buffered outputs into a 20-TSSOP — a channel density that saves board space in multi-loop control or waveform-generation applications where each output needs its own analog voltage. Settling to 0.5 LSB in 7 µs means the part can update all eight channels sequentially at roughly 140 kHz per channel, fast enough for servo-valve control, programmable power supplies, or audio-level setting without a dedicated fast-DAC bank.
Linearity and monotonicity for closed-loop systems
Integral nonlinearity of ±0.5 LSB and differential nonlinearity of ±0.1 LSB guarantee monotonic behavior — the output never decreases for an increasing digital code, a requirement in feedback loops where a non-monotonic step would cause oscillation or hunting. The string DAC architecture is inherently monotonic, and the tight DNL means the transfer function has no missing codes across the full 10-bit range — a calibration technician can trust the output step size without per-unit trimming.
Supply rails and interface fit
The SPI data interface uses standard 3- or 4-wire signaling and operates at clock rates up to 20 MHz (typical), so it connects directly to most MCU SPI peripherals without level shifters or glue logic at 3.3 V.
Temperature range and package for industrial boards
The 20-TSSOP body measures 6.5 mm × 4.4 mm with a 0.65 mm pin pitch — a footprint that routes easily on a two-layer board and leaves room for bypass capacitors and output filtering near each channel.
