Product details
Overview
The MAX4800ACCM+ from Maxim Integrated is an 8-channel, high-voltage SPST analog switch IC designed for ultrasound imaging and printer systems. It delivers low-charge-injection (≤600pC), 22Ω typical on-resistance, 20MHz SPI™ serial interface control, and supports ±100V/±15V/±160V high-voltage supply configurations with VPP–VNN ≤ 200V. Its role is to route high-voltage analog signals in transducer driver stages.
For engineers reviewing the MAX4800ACCM+ datasheet, MAX4800ACCM+ pinout, MAX4800ACCM+ application, or MAX4800ACCM+ equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases in medical imaging and industrial printing, and validated alternative options for design continuity.
Technical Context
The MAX4800ACCM+ implements a BCDMOS-based 8-bit serial shift register with transparent latch and power-on reset, enabling deterministic open-state initialization. Its digital interface operates independently from high-voltage supplies (VDD = +2.7V to +6V), while DIN/CLK/LE/CLR inputs are +6V tolerant regardless of VDD level.
Each channel features a low-capacitance (11pF off-capacitance), low-charge-injection SPST switch with DC–50MHz analog bandwidth, -77dB off-isolation at 5MHz, and turn-on/turn-off times of 5µs. The device supports asymmetric high-voltage rails (e.g., +40V/–160V) and includes integrated bleed resistors only in the MAX4802A variant - not in MAX4800ACCM+.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Count | 8 independent SPST analog switches |
| Max VPP–VNN | 200V - enables flexible high-voltage rail combinations including +100V/–100V, +40V/–160V |
| On-Resistance (TYP) | 22Ω at +25°C - ensures minimal signal attenuation and power loss in high-current transducer drive paths |
| Charge Injection | 600pC at +100V/–100V - critical for preserving signal integrity in precision ultrasound beamforming |
| Serial Interface Speed | 20MHz SPI™ - supports rapid reconfiguration of all 8 channels within 400ns per bit |
| Analog Bandwidth | DC to 50MHz - suitable for wideband ultrasonic pulse transmission and reception |
| Off-Isolation @ 5MHz | –77dB - suppresses crosstalk between adjacent channels during multi-element scanning |
Pinout & Package
MAX4800ACCM+ is packaged in a 48-pin LQFP (7mm × 7mm) with exposed pad, RoHS-compliant, and rated for 0°C to +70°C operation. Thermal resistance θJA = 44°C/W (four-layer board).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 10–12, 14, 16, 18, 20, 22, 25, 39, 41, 43, 45, 47 | COM0–COM7 / NO0–NO7 | Eight pairs of analog switch terminals - COMx is common, NOx is normally open; each pair handles bidirectional high-voltage signal routing |
| 24 | VPP | Positive high-voltage supply input - must be bypassed to GND with ≥0.1µF ceramic capacitor |
| 25 | VNN | Negative high-voltage supply input - supports –160V minimum; requires local bypassing |
| 28 | GND | Digital and analog ground reference - shared return for VDD, VPP, VNN bypass networks |
| 29 | VDD | +2.7V to +6V logic supply - powers internal shift register, latch, and interface circuitry |
| 33 | DIN | Serial data input - MSB-first 8-bit command stream controlling switch states |
| 34 | CLK | 20MHz serial clock input - rising edge clocks data into shift register and out via DOUT |
| 35 | LE | Latch-enable (active-low) - transfers shift register contents to output latch to update switch states |
| 36 | CLR | Latch clear (active-high) - resets all switches to open state without affecting shift register |
| 37 | DOUT | Serial data output - provides daisy-chain capability; reflects DIN delayed by 8 clocks |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Flexibility | VPP/VNN supports +100V/–100V, +40V/–160V, or +185V/–15V - eliminates need for custom power supplies in multi-platform designs |
| Low-Charge-Injection Switching | 600pC max at ±100V - minimizes transient voltage spikes that distort echo signals in ultrasound receivers |
| 20MHz SPI™ Serial Control | Enables full 8-channel configuration in ≤400ns - essential for real-time beam steering and dynamic aperture control |
| Power-On Reset | Guarantees all switches start open at power-up - prevents unintended high-voltage shorts during system boot |
| +6V-Tolerant Digital Inputs | DIN/CLK/LE/CLR accept up to +6V regardless of VDD - simplifies interfacing with 3.3V or 5V microcontrollers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HV2203FG-G | Pin-compatible but lacks 20MHz SPI™ interface; uses parallel 8-bit control; higher on-resistance (35Ω typ) | Requires additional address/control lines and PCB layout changes; unsuitable for space-constrained daisy-chained systems | Select HV2203FG-G only if legacy parallel interface compatibility is required and board area permits extra traces |
| MAX4802ACCM+ | Same pinout and package; adds integrated 35kΩ bleed resistors on all COM/NO terminals; identical electrical specs otherwise | Eliminates need for external discharge networks in piezo-driven systems; increases quiescent current slightly | Choose MAX4802ACCM+ when driving highly capacitive transducers where automatic load discharge is mandatory |
Compared with HV2203FG-G, MAX4800ACCM+ reduces control wiring complexity and improves update speed; compared with MAX4802ACCM+, it offers lower quiescent current and avoids unnecessary bleed resistor power dissipation in low-CLOAD applications.

FAQ
What is the maximum allowable voltage difference between VPP and VNN for MAX4800ACCM+?
The MAX4800ACCM+ specifies a maximum VPP–VNN differential of 200V. This allows configurations such as +100V/–100V, +40V/–160V, or +185V/–15V. Exceeding 200V violates absolute maximum ratings and risks permanent damage. The device does not require symmetrical rails, but both VPP and VNN must remain within their respective absolute limits (VPP ≤ VNN + 200V; VNN ≥ –160V).
Does MAX4800ACCM+ include integrated bleed resistors like the MAX4802A?
No, MAX4800ACCM+ does not include integrated bleed resistors. That feature is exclusive to the MAX4802A family (e.g., MAX4802ACCM+). When using MAX4800ACCM+ with capacitive loads such as piezoelectric transducers, external bleed networks must be added to safely discharge stored energy after switching.
What is the guaranteed on-resistance specification for MAX4800ACCM+ at +70°C?
At +70°C and VPP = +100V/VNN = –100V with ICOM = 5mA, the MAX4800ACCM+ guarantees RONS ≤ 30Ω (typical 22Ω). At ICOM = 200mA, RONS ≤ 27Ω. These values reflect worst-case conduction loss across temperature and current - critical for thermal management in high-duty-cycle ultrasound transmit stages.
Can MAX4800ACCM+ be daisy-chained with other devices?
Yes, MAX4800ACCM+ supports daisy-chaining via its DOUT pin. Connect DOUT of one device to DIN of the next, while sharing CLK, LE, and CLR across all units. A single 20MHz clock can configure multiple MAX4800ACCM+ devices sequentially, enabling scalable channel expansion without additional control lines.
What is the power-on behavior of MAX4800ACCM+ switches?
MAX4800ACCM+ incorporates a power-on reset circuit that forces all eight switches to the open (off) state at startup. This behavior is guaranteed regardless of VDD, VPP, or VNN ramp rates and prevents hazardous high-voltage shorts during system initialization - a critical safety feature in medical and industrial HV systems.
