526ksps, Single-Channel,
14-Bit, Parallel-Interface ADCs
General Description
Features
The MAX1319/MAX1323/MAX1327 are single-channel,
14-bit, 526ksps analog-to-digital converters (ADCs) with
2 ꢀLS ꢁIꢀ and 1 ꢀLS DIꢀ with no ꢂissing codesꢃ The
MAX1323 has a 5ꢄ inpꢅt range with 16ꢃ5ꢄ Vaꢅlt-toler-
ant inpꢅtsꢃ The MAX1327 has a 1ꢆꢄ inpꢅt range with
16ꢃ5ꢄ Vaꢅlt-tolerant inpꢅts and the MAX1319 has a ꢆ to
+5ꢄ inpꢅt range with 6ꢃꢆꢄ Vaꢅlt-tolerant inpꢅtsꢃ ꢇther
