Product details
Overview
MAX1197ECM from Maxim Integrated is a dual, 8-bit, 60Msps analog-to-digital converter optimized for low-power, high-dynamic-performance applications including baseband I/Q sampling, ultrasound imaging, and battery-powered instrumentation. It operates from a single 2.7V–3.6V supply, delivers 48.5dB SINAD at 30MHz input, features fully differential 400MHz (-3dB) T/H inputs, and integrates a 2.048V precision bandgap reference.
For engineers reviewing the MAX1197ECM datasheet, MAX1197ECM pinout, MAX1197ECM application, or MAX1197ECM equivalent, key selection considerations include its dual-channel matching (±0.05° phase, 0.05dB gain), parallel CMOS-compatible outputs with selectable two's complement/offset binary format, and support for internal, buffered external, or unbuffered external reference configurations.
Technical Context
The MAX1197ECM employs a seven-stage, fully differential pipelined architecture with 5-clock-cycle latency, enabling high-speed conversion while minimizing power. Each channel uses independent track-and-hold amplifiers with 400MHz full-power bandwidth and supports both differential and single-ended analog inputs referenced to COM.
Its reference system offers three configurable modes: internal (REFOUT→REFIN), buffered external (REFIN-driven), and unbuffered external (REFIN = GND), allowing flexible full-scale range adjustment. Digital outputs are CMOS-compatible, three-state, and powered by a separate 1.7V–3.6V OVDD supply for logic-level interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - fixed-precision quantization suitable for medium-dynamic-range signal acquisition in communications and imaging. |
| Sampling Rate | 60Msps - enables Nyquist-limited digitization of signals up to 30MHz, supporting IF sampling in WLAN/WWAN modems. |
| SINAD @ 30MHz | 48.5dB typical - defines usable dynamic range for 30MHz input tones; sufficient for 7–8 effective bits in demanding RF front ends. |
| Input Bandwidth | 400MHz (-3dB) - supports wideband analog input capture without external anti-alias filtering for undersampling applications. |
| Power Consumption | 120mW normal / 9mW sleep / 0.3µW shutdown - enables energy-constrained portable and battery-operated systems. |
| Channel Matching | ±0.05° phase / 0.05dB gain - ensures accurate I/Q signal reconstruction and minimal image rejection degradation in quadrature receivers. |
| Reference Voltage | 2.048V internal bandgap - provides stable, temperature-compensated full-scale range; ±3% tolerance over -40°C to +85°C. |
Pinout & Package
MAX1197ECM is housed in a 48-pin TQFP-EP (7mm × 7mm) package with exposed paddle for thermal management. Pin functions are validated per Maxim's official datasheet Rev 0 (19-2411).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+, INA- | Differential analog input Channel A | Accepts ±1VP-P differential or single-ended signals; requires matched impedance and VDD/2 common-mode bias for optimal performance. |
| INB+, INB- | Differential analog input Channel B | Independent second channel with identical AC specs; enables simultaneous I/Q or dual-sensor sampling. |
| CLK | Sampling clock input | CMOS-compatible rising-edge-triggered clock; jitter ≤2ps RMS required to preserve 48.5dB SINAD at Nyquist. |
| T/B | Output format select | High = two's complement; Low = straight offset binary - configures digital output coding without external logic. |
| OE | Output enable (active-low) | Controls three-state digital outputs D7A–D0A and D7B–D0B; allows bus sharing in multi-device systems. |
| PD, SLEEP | Power control inputs | PD high = 0.3µW shutdown; SLEEP high = 9mW sleep mode - supports dynamic power scaling in burst-mode operation. |
| REFP, REFN, COM | Reference interface nodes | Set full-scale range as ±(REFP–REFN); COM establishes mid-supply common-mode level for analog inputs. |
| D7A–D0A, D7B–D0B | Parallel digital outputs | Two independent 8-bit CMOS buses; OVDD-supplied (1.7V–3.6V) for direct interfacing with FPGA, ASIC, or microcontroller I/O. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent ADC channels | Enables true simultaneous sampling for I/Q demodulation or stereo sensor acquisition without time skew. |
| Configurable reference architecture | Supports internal, buffered external, or unbuffered external references - simplifies system-level accuracy calibration and range adaptation. |
| 5-clock-cycle deterministic latency | Allows precise timing alignment in closed-loop control or real-time DSP systems without variable pipeline delay compensation. |
| Interchannel crosstalk ≤ –72dB | Prevents signal leakage between channels at 20MHz, critical for high-fidelity dual-path signal processing in medical imaging. |
| Separate OVDD supply for digital outputs | Permits direct connection to 1.8V, 2.5V, or 3.3V logic families without level-shifting circuitry or signal integrity compromise. |
| On-chip 400MHz T/H amplifiers | Eliminates need for external high-speed input buffers in most RF and IF sampling applications, reducing BOM count and layout complexity. |

FAQ
What is the operating temperature range specified for the MAX1197ECM?
The MAX1197ECM is specified for the extended industrial temperature range of –40°C to +85°C, validated across all electrical parameters including SINAD, channel matching, and reference stability. This range supports deployment in outdoor wireless equipment, medical diagnostics hardware, and factory-floor instrumentation where ambient conditions vary widely. The MAX1197ECM maintains 48.5dB SINAD and ±0.05° phase matching across this full range.
Does the MAX1197ECM require an external reference, or does it include an internal one?
The MAX1197ECM includes an on-chip 2.048V precision bandgap reference, making external reference components optional. In internal reference mode, REFOUT is connected to REFIN via a 10kΩ resistor, and REFP/REFN/COM become low-impedance outputs. The MAX1197ECM also supports buffered and unbuffered external reference configurations for applications needing higher accuracy or custom full-scale ranges.
How does the MAX1197ECM handle dual-channel synchronization and matching?
The MAX1197ECM guarantees tight interchannel matching: 0.05dB gain difference and ±0.05° phase difference at 20MHz, measured under identical conditions with simultaneous capture. Its monolithic dual-pipeline architecture and shared clock/track-and-hold circuitry ensure deterministic timing alignment. The MAX1197ECM achieves –72dB interchannel crosstalk, preventing signal coupling that could degrade I/Q balance in quadrature receivers.
What power-saving modes does the MAX1197ECM support, and how quickly does it wake up?
The MAX1197ECM offers three power states: normal operation (120mW), sleep mode (9mW), and power-down mode (0.3µW). Wake-up time from sleep mode is 1µs; from shutdown, it is 20µs - both verified under full temperature range. These modes are controlled independently via SLEEP and PD pins, allowing fine-grained power management in burst-acquisition systems like radar or portable spectrum analyzers using the MAX1197ECM.
Can the MAX1197ECM interface directly with 1.8V logic, and what are the voltage requirements for its digital outputs?
Yes, the MAX1197ECM supports direct interfacing with 1.8V logic through its separate OVDD supply rail (1.7V–3.6V). When OVDD = 1.8V, VOH ≥ 1.6V and VOL ≤ 0.2V under 200µA load, meeting 1.8V CMOS input thresholds. The MAX1197ECM's three-state digital outputs (D7A–D0A/D7B–D0B) are fully compatible with FPGA, ASIC, and microcontroller I/O banks without level shifters - simplifying design and improving signal integrity.
