The 1:1 S/H-to-ADC ratio and external reference give the designer direct control over the input voltage span and the LSB size, matching the sensor's full-scale output without an external gain stage. ## Package, temperature, and what the 73k SPS rating means for your signal chain Housed in an 8-pin SOIC (0.154\" wide, 3.90 mm body), the surface-mount footprint is a standard JEDEC outline — no special land pattern or via-in-pad required. At 73k samples per second, the conversion time is roughly 13.7 µs — enough headroom to digitise a 10 kHz analog signal with Nyquist margin while leaving SPI bus cycles for the host to read the result and service other tasks.","metaTitle":"MAX1243BCSA+ ADC, 10-Bit SAR, 73k SPS, 8-SOIC","metaDescription":"Analog Devices MAX1243BCSA+ 10-bit SAR ADC, 73k SPS, single-ended input, SPI interface, 2.7-5.25V supply, 8-SOIC.
