MAXIM MAX1205 +5V Single-Supply 1Msps 14-Bit Self-Calibrating ADC handbook
Update: 30 September, 2023
The MAX1205 is a 14-bit monolithic analog-to-digital converter (ADC) capable of conversion rates up to 1Msps. This integrated circuit, built on a CMOS pro- cess, uses a fully differential, pipelined architecture with digital error correction and a short self-calibration procedure that corrects for capacitor and gain mis- matches and ensures 14-bit linearity at full sample rates. An on-chip track/hold (T/H) maintains superb dynamic performance up to the Nyquist frequency. The MAX1205 operates from a single +5V supply. The fully differential inputs allow an input swing of ±VREF. The reference is also differential, with the posi- tive reference (RFPF) typically connected to +4.096V and the negative reference (RFNF) connected to ana- log ground. Additional sensing pins (RFPS, RFNS) are provided to compensate for any resistive-divider action that may occur due to finite internal and external resis- tances in the reference traces and the on-chip resis- tance of the reference pins. A single-ended input is also possible using two operational amplifiers. The power dissipation is typically 257mW at +5V, at a sampling rate of 1Msps. The device employs a CMOS- compatible, 14-bit parallel, two’s complement output data format. For higher sampling rates, the MAX1201 is a 2.2Msps pin-compatible upgrade to the MAX1205.
