Analog Devices Inc./Maxim Integrated MAX1202EVL11-DIP

Overview

MAX1202EVL11-DIP from Maxim Integrated is an evaluation kit for the MAX1202 12-bit, 8-channel serial ADC with internal 4.096V reference, single +5V or dual ±5V analog supply support, and 3V-compatible digital interface (VL pin adjustable from 2.7V to 5.25V). It enables rapid validation of mixed 5V/3V data acquisition in battery-powered instruments and medical devices.

For engineers reviewing the MAX1202EVL11-DIP datasheet, MAX1202EVL11-DIP pinout, MAX1202EVL11-DIP application, or MAX1202EVL11-DIP equivalent, this kit provides immediate access to verified timing behavior (133ksps sampling), SPI/MICROWIRE/TMS320-compatible 4-wire serial interface operation, and power-down modes delivering <10μA supply current at reduced rates.

Technical Context

The MAX1202EVL11-DIP implements a successive-approximation ADC architecture with integrated track/hold, supporting both unipolar (0–VREF) and bipolar (±VREF/2) input ranges via software-configurable control byte. It uses either internal clock (1.7MHz typ.) or external serial clock up to 2MHz for conversion timing.

Its analog front-end accepts 8 single-ended or 4 differential inputs, with channel selection, polarity, and power-down mode all controlled via 8-bit serial command. The reference buffer (enabled by SHDN state and REFADJ configuration) supports internal compensation (SHDN = VDD) or external compensation (SHDN floating) modes.

FAQ

What is the MAX1202EVL11-DIP used for?

The MAX1202EVL11-DIP is an evaluation kit designed to validate the performance and interface behavior of the MAX1202 12-bit serial ADC. It provides a ready-to-use PCB with test points, proper decoupling, and a documented quick-look circuit (Figure 5 in datasheet) to verify sampling rate, INL (<±1 LSB), power-down current (<10μA), and SPI/MICROWIRE compatibility - all without custom layout effort. Engineers use MAX1202EVL11-DIP to confirm signal integrity and timing margins before committing to production design.

Does the MAX1202EVL11-DIP include the MAX1202 IC?

Yes, the MAX1202EVL11-DIP includes a populated MAX1202ACPP+ or MAX1202BCPP+ in 20-pin PDIP package, as specified in Maxim's ordering information and confirmed by the kit's schematic and bill of materials. It is not a blank board - the ADC is soldered and tested, with CH0–CH7, REF, VL, and digital interface pins brought out to headers or test points for direct probing and microcontroller connection.

Can the MAX1202EVL11-DIP support both unipolar and bipolar input modes?

Yes, the MAX1202EVL11-DIP fully supports both unipolar (0 to VREF) and bipolar (±VREF/2) input configurations via the MAX1202's software-selectable UNI/BIP bit in the 8-bit control byte. When used with the internal 4.096V reference, unipolar full-scale is +4.096V and bipolar full-scale is ±2.048V. The kit's reference circuitry (including 4.7μF capacitor at REF) ensures stable operation in both modes across temperature.

How does the VL pin function on the MAX1202EVL11-DIP?

On the MAX1202EVL11-DIP, the VL pin supplies the logic voltage for DOUT and SSTRB outputs, allowing direct interfacing with 3V, 3.3V, or 5V microcontrollers. The kit provides a dedicated jumper or test point to set VL between 2.7V and 5.25V - matching the MAX1202's specification - ensuring output VOH ≥ VL − 0.5V and VOL ≤ 0.4V under load, eliminating level-shifter requirements in mixed-voltage systems using MAX1202EVL11-DIP.

Is the MAX1202EVL11-DIP compatible with TMS320 DSPs?

Yes, the MAX1202EVL11-DIP supports direct connection to TMS320-family DSPs via its serial strobe (SSTRB) output, which pulses synchronously with conversion completion. In external clock mode, SSTRB asserts one SCLK period before the MSB appears on DOUT - matching TMS320 serial port timing requirements. The kit's wiring and decoupling preserve signal integrity for reliable handshaking without additional glue logic when evaluating MAX1202EVL11-DIP with C2000 or C5000 series processors.
