Product details
Overview
MAX1196ECM from Maxim Integrated is a dual 8-bit, 40Msps analog-to-digital converter optimized for low-power, high-dynamic-performance signal acquisition in imaging and communications systems. It features fully differential track-and-hold inputs with 400MHz (-3dB) input bandwidth, internal 2.048V precision bandgap reference, and multiplexed parallel CMOS outputs. It operates from a single 2.7V–3.6V analog supply and delivers 48.4dB SINAD at 20MHz input frequency.
For engineers reviewing the MAX1196ECM datasheet, MAX1196ECM pinout, MAX1196ECM application, or MAX1196ECM equivalent, this page provides verified technical context, exact pin functions, channel-matching specifications, power-mode timing, and validated alternatives for baseband I/Q sampling, ultrasound imaging, and battery-powered instrumentation designs.
Technical Context
The MAX1196ECM employs a 7-stage fully differential pipelined architecture with 5-cycle latency for Channel A and 5.5-cycle latency for Channel B. Input sampling occurs on both rising and falling edges of the 40MHz clock, with data multiplexed to shared D0A/B–D7A/B outputs controlled by the A/B indicator pin.
Its dual-input T/H circuitry supports both differential (±1VP-P) and single-ended operation, with matched gain (±0.05dB) and phase (±0.05°) between channels. The internal reference structure allows flexible configuration-internal, buffered external, or unbuffered external-enabling full-scale range adjustment while maintaining ±100ppm/°C temperature stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1195ECM | Same pinout, identical architecture, but rated for 40Msps with tighter production test limits on SNR/SFDR at high frequencies. | Preferred where production-grade 48.4dB SINAD at 200MHz input is required; lacks extended temperature validation beyond +85°C. | Select MAX1195ECM when full industrial temp range is not needed and higher factory-tested dynamic performance is prioritized. |
| MAX1186ECM | 10-bit resolution, same 48-pin TQFP package; N.C. pins internally pulled to GND, enabling drop-in replacement with no layout change. | Used where higher resolution (10-bit) is needed for improved dynamic range in lower-frequency (<10MHz) instrumentation applications. | Choose MAX1186ECM when upgrading resolution without redesigning PCB; verify that 10-bit latency (6.5 cycles) meets system timing budget. |
Compared with MAX1195ECM, MAX1196ECM guarantees extended industrial temperature operation (-40°C to +85°C) and includes validated crosstalk (-72dB) and matching specs; compared with MAX1186ECM, it trades 2-bit resolution for 2× higher sampling throughput and lower power at 40Msps.

FAQ
What is the maximum analog input frequency supported by the MAX1196ECM?
The MAX1196ECM has a full-power bandwidth of 400MHz (-3dB), allowing accurate digitization of analog inputs up to ~150MHz without significant amplitude loss. Its small-signal bandwidth extends to 500MHz, supporting high-fidelity capture of narrowband IF signals. Performance metrics like SINAD and SFDR are specified up to 200MHz, with 48.4dB SINAD confirmed at 20MHz and 48dB at 101MHz. The MAX1196ECM maintains usable dynamic range well beyond its Nyquist limit due to its wideband T/H amplifier design.
How does the MAX1196ECM handle dual-channel data output?
The MAX1196ECM uses a multiplexed parallel output scheme: both Channel A and Channel B share the same D0A/B–D7A/B bus, with the A/B pin indicating active channel (A/B = 1 for CHA, A/B = 0 for CHB). CHA data updates on the rising edge of CLK after 5 clock cycles; CHB updates on the falling edge after 5.5 cycles. This architecture reduces pin count and simplifies FPGA/ASIC interface logic while preserving channel timing coherence. The MAX1196ECM's A/B output has a typical 6ns delay relative to CLK, ensuring predictable data-valid windows.
Can the MAX1196ECM operate with an external reference voltage?
Yes, the MAX1196ECM supports three reference modes: internal (2.048V bandgap), buffered external (REFIN driven with 2.048V), and unbuffered external (voltage applied directly to REFP/REFN/COM). In buffered mode, REFIN accepts 2.048V with >50MΩ input resistance; in unbuffered mode, REFP and REFN accept ±10% differential range (1.024V ±10%) with 4kΩ input resistance. The MAX1196ECM's reference flexibility allows full-scale range adjustment from ±0.5V to ±1.0V while maintaining ±100ppm/°C stability and noise performance.
What power-saving modes does the MAX1196ECM provide?
The MAX1196ECM offers three power states: normal operation (87mW), sleep mode (9mW via SLEEP pin), and shutdown mode (0.3µW via PD pin). Sleep mode disables ADC conversion but keeps the reference bias active for fast wake-up (<1µs); shutdown mode powers down all circuits except the PD input receiver. Wake-up from shutdown takes ≤20µs. All modes are asynchronous and controllable independently of the clock. The MAX1196ECM's low quiescent current supports energy harvesting and battery-operated systems requiring microamp-level standby consumption.
Is the MAX1196ECM pin-compatible with other devices in the MAX119x family?
Yes, the MAX1196ECM is pin-compatible with the MAX1195ECM (40Msps), MAX1197ECM (60Msps), and MAX1198ECM (100Msps), enabling speed upgrades without PCB redesign. It is also pin-compatible with the 10-bit MAX1186ECM, where unused N.C. pins are internally pulled to ground-making the MAX1196ECM a drop-in replacement for MAX1186ECM in 8-bit applications. All share the same 48-pin TQFP-EP package, identical pin functions, and compatible power/reference interface requirements.
