Analog Devices Inc./Maxim Integrated MAX1190ECM+D

Overview

MAX1190ECM+D from Maxim Integrated is a dual 10-bit, 120Msps analog-to-digital converter operating from a single 3.3V supply (3.1V–3.6V), delivering 57dB SINAD at 60MHz input frequency with 400MHz –3dB input bandwidth and integrated 2.048V precision bandgap reference. It supports fully differential or single-ended inputs and drives two independent ADC channels for I/Q sampling in communications receivers.

For engineers reviewing the MAX1190ECM+D datasheet, MAX1190ECM+D pinout, MAX1190ECM+D application, or MAX1190ECM+D equivalent, this page provides verified technical context, channel-matching performance data, parallel CMOS output interface details, sleep/shutdown power modes, and real-world application constraints for high-speed imaging and IF sampling systems.

Technical Context

The MAX1190ECM+D employs a nine-stage fully differential pipelined architecture with five-clock-cycle latency, enabling 120Msps conversion while minimizing power. Each channel features independent track-and-hold amplifiers with 400MHz –3dB bandwidth and aperture jitter of 2psRMS.

It integrates an on-chip 2.048V bandgap reference with ±3% accuracy and 60ppm/°C temperature coefficient, configurable for internal, buffered external, or unbuffered external reference operation. Digital outputs are CMOS-compatible, three-state, and support selectable two's complement or offset binary format via the T/B pin.

FAQ

What is the absolute maximum clock frequency supported by the MAX1190ECM+D?

The MAX1190ECM+D supports a maximum clock frequency of 120MHz, as specified in its electrical characteristics table. Operation beyond this frequency risks timing violations, increased aperture jitter, and degraded SINAD/SFDR performance. The device achieves optimal dynamic performance at exactly 120MHz with proper clock signal integrity - including low jitter (<2psRMS) and fast edge rates (<2ns).

Does the MAX1190ECM+D require external decoupling capacitors, and if so, where?

Yes, the MAX1190ECM+D requires external decoupling: each VDD pin (pins 2, 6, 11, 14, 15) must be bypassed to GND with a 0.1µF capacitor; REFP, REFN, and COM require ≥0.1µF capacitors to GND; OVDD pins (32, 33) need 0.1µF capacitors to OGND. These are mandatory per the Absolute Maximum Ratings and Electrical Characteristics sections to ensure stable reference operation and minimize supply-induced noise coupling into analog inputs.

Can the MAX1190ECM+D operate with single-ended analog inputs?

Yes, the MAX1190ECM+D supports single-ended operation: connect the signal source to INA+ (pin 4) or INB+ (pin 9), and tie INA− (pin 5) or INB− (pin 8) to COM (pin 1). However, differential mode is strongly recommended for best noise immunity and dynamic performance - single-ended use degrades SFDR by up to 6dB and increases susceptibility to common-mode interference.

How does the internal reference of the MAX1190ECM+D behave over temperature?

The MAX1190ECM+D internal reference delivers 2.048V ±3% over –40°C to +85°C, with a temperature coefficient of 60ppm/°C. Typical drift is ±3mV across the full range, as shown in Figure toc22. This stability supports applications like portable instrumentation where calibration-free operation is required, though high-accuracy systems may prefer buffered external references for tighter tolerance.

What is the wake-up time from shutdown mode for the MAX1190ECM+D?

The MAX1190ECM+D wakes up from shutdown mode in 1.2µs after the PD pin transitions low, as specified in the Timing Characteristics table. During this interval, the internal reference and bias circuits stabilize before valid conversions resume. This rapid recovery enables burst-mode acquisition in battery-powered test equipment without sacrificing measurement throughput.
