Evaluates: MAX1191/MAX1192/MAX1193 19-2958 Rev 0 7/03 MAX1193 Evaluation Kit General Description Features The MAX1193 evaluation kit (EV kit) is a fully assembled Up to 45Msps Sampling Rate (MAX1193) and tested circuit board that contains all the components Ultra-Low-Power Operation necessary to evaluate the performance of the MAX1191/ MAX1192/MAX1193 dual, 8-bit analog-to-digital convert- Single-Ended or Fully Differential Input Signal ers (ADCs). The MAX1191/MAX1192/MAX1193 accept Configuration AC- or DC-coupled, differential, or single-ended analog AC- or DC-Coupled Input Configuration inputs. The digital output produced by the ADC can be easily captured with a user-provided high-speed logic Configurable Reference Voltage analyzer or data acquisition system. The EV kit operates On-Board Clock-Shaping Circuit from a 3.3V analog and a 2.5V digital power supply. The EV kit includes circuitry that generates a clock signal from Fully Assembled and Tested an AC sine wave signal provided by the user. The EV kit comes with the MAX1193 installed.

DESIGNATION QTY DESCRIPTION 3) Verify that a shunt is installed across pins 1 and 2 of jumper JU11 (internal reference mode). Buffer/drivers tri-state output (48-pin TSSOP) 4) Connect the logic analyzer to header J1. Both U3 1 Texas Instruments channel A and channel B data signal are multi- SN74ALVCH16244DGG plexed on header J1. Control signal A/ B on pin J1J11 indicates whether data is from channel A C LKIN, D /E I NA, (high) or from channel B (low).
