MAXIM INTEGRATED PRODUCTS MAX1144/MAX1145 Manual
Update: 30 September, 2023
MAX1144/MAX1145 are 150ksps, 14-bit ADCs. These serially interfaced ADCs connect directly to SPI™, QSPI™, and MICROWIRE™ devices without external logic. They combine an input scaling network, internal track/hold, clock, and three general-purpose digital output pins (for external multiplexer or PGA con- trol) in a 20-pin SSOP package. The excellent dynamic performance (THD ≥ 90dB), high speed (150ksps in bipolar mode), and low power (8.0mA) of these ADCs make them ideal for applications such as industrial process control, instrumentation, and medical applica- tions. The MAX1144 accepts input signals of 0 to +6V (unipo- lar) or ±6V (bipolar), while the MAX1145 accepts input signals of 0 to +2.048V (unipolar) or ±2.048V (bipolar). Operating from a single 3.135V to 3.465V analog digital supply, powerdown modes reduce current consump- tion to 0.15mA at 10ksps and further reduce supply current to less than 20µA slower data rates. A serial strobe output (SSTRB) allows direct connection to the TMS320 family digital-signal processors. The MAX1144/MAX1145 user can select either the internal clock or an external serial-interface clock for the ADC to perform analog-to-digital conversions. The MAX1144/MAX1145 feature internal calibration cir- cuitry to correct linearity and offset errors. On-demand calibration allows the user to optimize performance. Three user-programmable logic outputs are provided for the control of an 8-channel mux or PGA. The MAX1144/MAX1145 a
