3 MSPS in a TSOT-23-6 — the speed-to-footprint ratio
The AD7277AUJZ-500RL7 is a 10-bit successive-approximation-register (SAR) ADC that samples at 3 MSPS. That sampling rate in a TSOT-23-6 package means you can digitize a 1.5 MHz bandwidth signal (Nyquist-limited) from a board area smaller than a grain of rice — useful when channel density or probe-tip placement drives the layout. The single-ended input with a 1:1 S/H-to-ADC ratio and a single supply rail (2.35 V to 3.6 V for both analog and digital,) keeps the power tree simple: one LDO or battery cell feeds the whole ADC, and the reference is the supply itself. No external reference IC needed, but the supply noise directly couples into the conversion — a clean rail matters more here than with a band-gap-referenced part.
SPI/DSP interface and temperature grade
Data is read out over a SPI or DSP-compatible serial interface — three wires (SCLK, SDATA, CS) plus the supply. The 3 MSPS throughput at 10 bits means the serial clock runs at least 30 MHz to keep the bus from bottlenecking the conversion rate.
Active production, ROHS3, and sourcing
Available in Tape & Reel (TR) or Cut Tape (CT) options — the reel suits automated pick-and-place for volume builds; the cut tape works for prototypes or small-batch rework.
