Product details
Overview
The MAX9505ETE+T from Maxim Integrated is a DirectDrive™ video amplifier with integrated reconstruction filter and analog switch, designed for standard-definition video signal conditioning in space-constrained portable systems. It provides 6dB gain, DC-coupled output with black level set to ground, 50dB attenuation at 27MHz, and 1.7Ω on-resistance analog switching - enabling direct connection to video DACs and multimedia jacks in mobile phones and handheld AV devices.
For engineers reviewing the MAX9505ETE+T datasheet, MAX9505ETE+T pinout, MAX9505ETE+T application, or MAX9505ETE+T equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, functional mode behavior, and real-world use context for video signal path design, multimedia jack interface, and low-power shutdown implementation.
Technical Context
The MAX9505ETE+T integrates three core subsystems: a 6dB video amplifier with DirectDrive charge-pump/linear regulator generating –2V rail for true ground-referenced sync; a six-pole Butterworth reconstruction filter (–3dB at 9MHz, 50dB attenuation at 27MHz); and a digitally controlled 1.7Ω analog switch supporting normal (0V to VDD) and extended-range (–2V to VDD) operation via MODE0/MODE1 logic inputs.
It operates from a single 2.7V–3.6V supply, achieves ±1dB passband flatness to 5.5MHz, delivers 0.1% differential gain error and 0.2° differential phase error under NTSC conditions, and enters sub-10nA shutdown current when both MODE0 and MODE1 are low - making it suitable for battery-powered video output and shared-jack audio/video routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V to 3.6V single supply - eliminates need for dual-rail supplies in portable designs. |
| Video Gain | 6dB (5.5–6.5dB typical) - matches standard video DAC output levels to 1VP-P into 150Ω load. |
| Reconstruction Filter | 6-pole Butterworth, –3dB at 9MHz, 50dB attenuation at 27MHz - suppresses DAC image artifacts without degrading baseband fidelity. |
| Analog Switch RON | 1.7Ω max (MODE1=VDD, MODE0=VDD) - ensures minimal insertion loss and distortion in video/audio signal paths. |
| Shutdown Current | 10nA typical - enables ultra-low-power state during display off or jack reconfiguration. |
| Output Black Level | 0V ±0.1V (at VDD = 2.7V) - sets sync tip at ground, eliminating AC-coupling capacitors and associated sag/distortion. |
| Differential Gain/Phase | 0.1% / 0.2° (NTSC, 2VP-P) - meets broadcast-quality video linearity requirements for portable displays. |
Pinout & Package
The MAX9505ETE+T is housed in a 16-pin TQFN package (3mm × 3mm, 0.8mm height) with exposed paddle (EP) connected to GND. Pin numbering follows JEDEC MO-220, with Pin 1 at top-left corner adjacent to notch/mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 13) | Positive power supply input | 2.7V–3.6V main supply; bypassed with 1µF capacitor to SGND for noise suppression. |
| VIDIN (Pin 9) | Video signal input | Accepts DC-coupled video from DAC; high-impedance (1MΩ) input minimizes loading. |
| VIDOUT (Pin 15) | Filtered/amplified video output | Direct-drive output swings ±0.3V to +0.7V; requires 75Ω back-termination for impedance matching. |
| SIN (Pin 16) | Analog switch input | Supports video input, video output, or mic input depending on MODE0/MODE1 configuration. |
| SOUT (Pin 14) | Analog switch output | Routes selected signal pole to external 4-pole multimedia jack; low RON preserves signal integrity. |
| MODE0 / MODE1 (Pins 10/11) | Operating mode control inputs | Two-bit logic selects shutdown, video output, normal switch, or extended-range switch mode per Table 1. |
| CPVDD / CPVSS / CPGND / C1P / C1N (Pins 6/1/4/5/3) | Charge-pump support terminals | Enable internal –2V rail generation; require 1µF flying and bypass capacitors for stable negative supply. |
| BIAS (Pin 7) | Common-mode voltage reference | Set to 1V via 100kΩ resistor to SGND; defines amplifier input common-mode point. |
Key Features

FAQ
What is the function of the MODE0 and MODE1 pins on the MAX9505ETE+T?
The MODE0 and MODE1 pins on the MAX9505ETE+T configure four operating modes: shutdown (both low), extended-range switch (MODE0 high, MODE1 low), video output (MODE0 low, MODE1 high), and normal switch (both high). These pins control activation of the video amplifier, charge pump, and analog switch independently - enabling flexible power and signal routing management in shared-jack architectures. The MAX9505ETE+T uses these inputs to avoid external logic or firmware overhead for mode selection.
Does the MAX9505ETE+T require external capacitors for its charge-pump circuit?
Yes, the MAX9505ETE+T requires four external 1µF ceramic capacitors: two for charge-pump flying (C1P–C1N) and bypass (CPVDD–CPGND), one for bias reference (BIAS–SGND), and one for main supply (VDD–SGND). These are mandatory for stable –2V rail generation and noise-free video output; omitting any compromises DirectDrive functionality and may cause sync-level instability or increased THD+N. The MAX9505ETE+T datasheet specifies X5R/X7R dielectrics with ≤100mΩ ESR.
Can the MAX9505ETE+T drive a 75Ω coaxial cable directly?
Yes, the MAX9505ETE+T is designed to drive 75Ω loads directly, with VIDOUT specified for 150Ω termination to SGND (equivalent to 75Ω differential). Its output stage delivers 2.594VP-P swing into 150Ω and features 0.5Ω output impedance at 5MHz, ensuring minimal mismatch loss and group delay distortion. For optimal performance, a 75Ω back-termination resistor must be placed adjacent to the MAX9505ETE+T output pin - the MAX9505ETE+T itself does not include internal 75Ω termination.
How does the MAX9505ETE+T achieve DC-coupled video output without large capacitors?
The MAX9505ETE+T achieves DC-coupled video output using DirectDrive™ technology: an integrated inverting charge pump generates a clean –2V rail, and a linear regulator filters its ripple. This negative supply allows the amplifier's output stage to swing below ground, fixing the video black level at 0V and eliminating the need for series coupling capacitors. The MAX9505ETE+T sustains this operation with <30mV peak-to-peak noise injection - visibly imperceptible in displayed video.
What is the maximum analog signal range supported by the MAX9505ETE+T's analog switch in extended-range mode?
In extended-range switch mode (MODE1 = low, MODE0 = high), the MAX9505ETE+T's analog switch supports an input voltage range of –2V to VDD, enabling bidirectional signal routing that includes sync pulses below ground - critical for composite video signals where sync tips fall to –0.3V. This mode activates the charge pump but disables the video amplifier, allowing the switch to pass full-swing video or audio without distortion. The MAX9505ETE+T maintains 1.7Ω RON and <20pC charge injection across this extended range.
