14-bit, 135 kSPS ADC — what the rating means for your signal chain
The MAX1158BCUP is a 14-bit successive-approximation ADC with a 135 kSPS throughput rate — the conversion time per sample is roughly 7.4 µs, which sets the Nyquist ceiling for the input signal bandwidth at about 67 kHz before aliasing becomes a concern. At 14-bit resolution, the LSB size for a typical 5 V reference is 305 µV — this determines the noise floor the front-end conditioning must stay below to avoid dithering the last bit.
Bulk packaging — what it signals for procurement
Shipped in Bulk (tubes or tray), not tape-and-reel — this is the standard format for prototype quantities and low-volume production runs where pick-and-place throughput is not the bottleneck. For high-volume reflow assembly, factor in the cost of tube-to-reel transfer or confirm your CM can handle tube-fed feeders — Bulk packaging adds a handling step that tape-and-reel avoids.
