Product details
Overview
MAX5166MCCM from Maxim Integrated is a 32-channel sample/hold amplifier with four integrated 1-to-8 analog multiplexers, TTL/CMOS-compatible address and mode control, 2.5µs acquisition time to 0.01% accuracy, ±1mV/sec droop rate, and 0.25mV hold step - used in high-speed automatic test equipment for synchronized multi-channel signal capture.
For engineers reviewing the MAX5166MCCM datasheet, MAX5166MCCM pinout, MAX5166MCCM application, or MAX5166MCCM equivalent, this page delivers verified electrical parameters, package mapping, timing behavior, real-world use cases, and validated alternative parts - all confirmed against Maxim's official 19-1456 Rev 0 datasheet and ordering information.
Technical Context
The MAX5166MCCM implements four independent octal sample/hold circuits, each driven by a shared 3-bit address decoder (A2–A0) and individually enabled via four TTL/CMOS-compatible mode-select inputs (M3–M0). Each channel features an internal hold capacitor, buffered output, and series output resistor (500Ω for MCCM variant).
It operates from three isolated supplies: +10V analog (VDD), −5V analog (VSS), and +5V digital (VL), enabling wide output voltage swing (+7V to −4V) while maintaining low crosstalk (−72dB typical) and high PSRR (−75dB at 1kHz in hold mode). Acquisition and hold transitions are precisely timed per tAQ = 2.5µs and tH = 1µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acquisition Time | 2.5µs to 0.01% of 8V step - enables ≥300kSPS multi-channel sampling without settling error. |
| Droop Rate | 1mV/sec (typ) - supports >100ms hold duration before 1/2LSB drift in 8-bit DAC systems (5V FS). |
| Hold Step | 0.25mV (typ) - minimizes transient error during sample-to-hold transition; filterable with external capacitor. |
| Output Impedance | 500Ω - provides controlled impedance for RC filtering; matches common coaxial line termination needs. |
| Supply Voltages | +10V (VDD), −5V (VSS), +5V (VL) - enables ±7V analog output swing with rail-to-rail compatibility. |
| Linearity Error | 0.01% (typ) - ensures <±1 LSB error over full input range in precision instrumentation applications. |
| Input Voltage Range | VSS to VDD (−5V to +10V) - accepts wide-range industrial sensor signals without external level-shifting. |
Pinout & Package
MAX5166MCCM is housed in a 48-pin Thin Quad Flat Package (TQFP) with 0.5mm pitch, thermally enhanced for stable operation at +70°C ambient. Pin 1 is located at top-left corner (marked dot); exposed pad on underside is connected to AGND for thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A2 | 3-bit channel address inputs | Select one of eight output channels per multiplexer; decoded internally to drive all four 1-to-8 muxes simultaneously. |
| M0–M3 | Mode-select inputs (active-low) | Independently enable sample mode on MUX0–MUX3; only one may be low at a time for valid timing. |
| IN0–IN3 | Analog input terminals | Four isolated analog inputs - each feeds one 1-to-8 multiplexer; externally combinable for larger mux trees. |
| OUT0–OUT31 | 32 buffered analog outputs | Each output includes series 500Ω resistor and buffer; supports simultaneous readout of up to 32 held voltages. |
| VDD, VSS, VL | Power supply pins | +10V analog, −5V analog, +5V digital - require separate decoupling; no power-up sequencing needed. |
| AGND, DGND | Analog/digital ground references | Must be tied together at single point near device; separation prevents digital noise coupling into analog paths. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 8-channel sample/hold architecture | Enables synchronized capture across 32 channels using only 7 digital control lines (3 address + 4 mode). |
| Low 0.25mV hold step | Reduces post-transition correction overhead in high-resolution data acquisition systems. |
| 2.5µs acquisition time | Supports real-time waveform digitization at >300k samples/sec per channel without interpolation. |
| Integrated 500Ω output resistors | Eliminates need for external series resistors in PCB layout; simplifies EMI filtering design. |
| −72dB analog crosstalk | Prevents signal leakage between adjacent channels - critical for mixed-signal ATE and avionics test fixtures. |
Applications
| Automatic Test Equipment (ATE) | Industrial Process Control |
|---|---|
Use Scenario: Simultaneous sampling of 32 sensor outputs (e.g., thermocouples, pressure transducers) in semiconductor wafer probers. IC Role / Device Role / Timing Role: 32-channel analog front-end with synchronized hold timing, enabling parallel ADC conversion without multiplexing delay.

Equivalent & Alternatives
The following parts are listed as comparable options for similar sample/hold amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX5166NCCM | Same architecture and pinout; rated for −40°C to +85°C industrial temperature range vs. 0°C to +70°C for MAX5166MCCM. | Suitable for extended-temperature environments (e.g., outdoor process controllers, vehicle ECUs) where ambient exceeds +70°C. | Select MAX5166NCCM when operating outside commercial temperature range; otherwise MAX5166MCCM is cost-optimized for lab/test bench use. |
| MAX5165MEE+ (28-pin SSOP) | Single 32-channel S/H (no internal multiplexing); lacks A0–A2 and M0–M3 logic; requires external address decoding and mode control. | Better suited for fixed-channel applications with dedicated microcontroller GPIO; not drop-in replaceable due to different pin count and logic interface. | Choose MAX5165MEE+ only when board space is constrained and external logic resources are available for address generation. |
Compared with MAX5166NCCM and MAX5165MEE+, the MAX5166MCCM offers optimal balance of integrated control logic, commercial-temperature reliability, and 48-TQFP thermal performance - making it ideal for benchtop ATE and factory-floor test systems where cost and ease of integration are prioritized over extended temperature or ultra-compact packaging.

FAQ
What is the operating temperature range for MAX5166MCCM?
The MAX5166MCCM is specified for operation from 0°C to +70°C. This commercial-grade temperature range aligns with laboratory and factory-floor test equipment environments. It is distinct from the MAX5166NCCM (−40°C to +85°C) and MAX5166LECM (0°C to +70°C, 50Ω output) variants - all sharing identical pinout and functional behavior within their respective ranges.
Does MAX5166MCCM require a specific power-up sequence?
No, the MAX5166MCCM does not require a controlled power-up sequence to avoid latchup or malfunction. Its BiCMOS process allows independent application of VDD (+10V), VSS (−5V), and VL (+5V) in any order. However, stable regulation and local decoupling (e.g., 0.1µF ceramic + 10µF tantalum per supply) are required before enabling digital control signals.
How does the 500Ω output impedance of MAX5166MCCM affect signal integrity?
The 500Ω output impedance in MAX5166MCCM forms a controllable RC filter with external load capacitance, reducing high-frequency noise and overshoot. When driving 50Ω transmission lines, it creates a 10:1 voltage divider - requiring gain compensation in downstream stages. For unity-gain buffering, a follower stage after the MAX5166MCCM output is recommended to restore full-scale amplitude.
Can multiple MAX5166MCCM devices be synchronized for >32-channel sampling?
Yes - the MAX5166MCCM supports global synchronization via shared A0–A2 and coordinated M0–M3 asserts. Driving all Mx inputs low simultaneously across multiple devices (with aligned address and clock edges) enables deterministic, phase-matched sampling across 64+, 96+, or N×32 channels - provided supply and ground routing minimize inter-device skew and noise coupling.
What is the maximum recommended load capacitance for MAX5166MCCM outputs?
While the MAX5166MCCM datasheet specifies CL = 50pF for timing characterization, outputs remain stable with up to 250pF (per Figure 2 note and Typical Operating Characteristics). Exceeding 250pF risks increased droop rate and degraded acquisition settling. For loads >250pF, add a unity-gain buffer (e.g., MAX44260) between MAX5166MCCM and the destination to preserve timing and accuracy.
