Product details
Overview
MAX4133ESD from Maxim Integrated is a dual, rail-to-rail input/output operational amplifier optimized for low-voltage, single-supply precision signal conditioning. It delivers 10MHz gain-bandwidth, 900µA per amplifier quiescent current, ±0.25mV typical input offset voltage (25°C), shutdown capability reducing supply current to 25µA per amplifier, and full rail-to-rail swing into 250Ω loads - enabling use in battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4133ESD datasheet, MAX4133ESD pinout, MAX4133ESD application, or MAX4133ESD equivalent, key selection criteria include its dual-channel configuration with independent shutdown control, SO-14 package compatibility, guaranteed -40°C to +85°C operation, and verified stability with 160pF capacitive loads - critical for sensor interface and portable instrumentation designs.
Technical Context
The MAX4133ESD integrates two fully independent high-speed op amps in a single SO-14 package, each featuring complementary NPN/PNP rail-to-rail input stages extending common-mode range 200mV beyond VEE and VCC, and a robust rail-to-rail output stage capable of driving 250Ω loads with <150mV headroom at both rails. Its architecture supports unity-gain stability without external compensation.
Each amplifier includes a dedicated SHDN pin (SHDN1 and SHDN2) enabling independent power gating; when asserted low (<0.8V), output enters high-impedance state and ICC drops to ≤40µA per amplifier (–40°C to +85°C). The device operates from +2.7V to +6.5V single supply or ±1.35V to ±3.25V dual supplies, with CMVR spanning VEE – 0.20V to VCC + 0.20V across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 10MHz - enables stable closed-loop operation up to ~1MHz with gain ≥10, suitable for anti-aliasing and active filtering in 100ksps data converters. |
| Supply Current per Amplifier | 900µA typical at +2.7V - allows dual-channel amplification in sub-2mA total system budget for coin-cell-powered devices. |
| Input Offset Voltage | ±0.25mV (typ) / ±0.75mV (max) at 25°C - ensures ≤0.5LSB error in 12-bit systems with 2V full-scale range. |
| Output Voltage Swing | Within 125mV of rails into 250Ω load - preserves dynamic range in 3.3V or lower single-supply systems without level-shifting. |
| Capacitive-Load Stability | Stable with up to 160pF - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
| Shutdown Supply Current | ≤40µA per amplifier at +5V - reduces standby power by >95% versus active mode, critical for duty-cycled sensor nodes. |
| Common-Mode Rejection Ratio | 74dB min (25°C), 74dB min (–40°C to +85°C) - suppresses supply ripple and ground noise in noisy embedded environments. |
Pinout & Package
MAX4133ESD is housed in a 14-pin small-outline (SO) package with standard JEDEC MS-012AC footprint (5.0mm × 10.2mm body, 1.27mm pitch). Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load or feedback network; high-impedance during SHDN1 assertion. |
| 2 | IN1− | Inverting input for Amp 1 - accepts differential or single-ended signals; protected by 1kΩ series resistors and back-to-back diodes. |
| 3 | IN1+ | Noninverting input for Amp 1 - rail-to-rail common-mode range (VEE − 0.2V to VCC + 0.2V) enables direct sensor interfacing. |
| 4 | VEE | Negative supply - tied to GND for single-supply operation; serves as reference for rail-to-rail output swing. |
| 5 | VCC | Positive supply - accepts +2.7V to +6.5V; requires 0.1µF ceramic + ≥1µF bulk bypassing for stability. |
| 6 | IN2+ | Noninverting input for Amp 2 - electrically identical to IN1+; supports dual-channel signal conditioning in one IC. |
| 7 | IN2− | Inverting input for Amp 2 - matched bias current and impedance to IN1− for consistent channel performance. |
| 8 | OUT2 | Amplifier 2 output - independent of OUT1; enables simultaneous processing of two analog channels. |
| 9 | N.C. | No connection - not internally bonded; must remain unconnected on PCB. |
| 10 | SHDN2 | Shutdown control for Amp 2 - logic-low (<0.8V) disables Amp 2; floating or ≥2.0V enables operation. |
| 11 | N.C. | No connection - not internally bonded; must remain unconnected on PCB. |
| 12 | N.C. | No connection - not internally bonded; must remain unconnected on PCB. |
| 13 | SHDN1 | Shutdown control for Amp 1 - independent of SHDN2; enables selective power gating per channel. |
| 14 | N.C. | No connection - not internally bonded; must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 200mV beyond VEE/VCC and output swings within 125mV of rails into 250Ω - maximizes usable dynamic range in 3.3V/2.7V systems. |
| Independent shutdown | Dual SHDN pins (SHDN1/SHDN2) allow per-amplifier power control - reduces system-level standby current without disabling entire signal chain. |
| 160pF capacitive-load stability | Eliminates need for output isolation resistors when driving ADC inputs or long traces - simplifies layout and preserves bandwidth. |
| Low input offset drift | ±2µV/°C tempco - limits offset-induced error to <1mV over full –40°C to +85°C range, critical for uncalibrated industrial sensors. |
| Unity-gain stable | Operates stably at AV = 1 without external compensation - enables simple buffer, follower, and active filter configurations. |

FAQ
What is the operating temperature range for MAX4133ESD?
The MAX4133ESD is specified for continuous operation from –40°C to +85°C. All electrical parameters in the datasheet - including input offset voltage (±0.75mV max), supply current (900µA typ), and CMRR (74dB min) - are guaranteed across this full industrial temperature range, making MAX4133ESD suitable for harsh-environment deployments like factory automation and outdoor instrumentation.
Does MAX4133ESD support true rail-to-rail input and output operation?
Yes, MAX4133ESD provides true rail-to-rail input common-mode voltage range (VEE – 0.20V to VCC + 0.20V) and rail-to-rail output voltage swing (within 125mV of VEE/VCC into 250Ω). This is achieved via complementary NPN/PNP input stages and a robust output stage, allowing MAX4133ESD to condition signals directly at supply rails - essential for maximizing dynamic range in 2.7V–3.3V systems.
How does the shutdown feature work on MAX4133ESD?
MAX4133ESD features two independent shutdown pins: SHDN1 (pin 13) controls amplifier 1, and SHDN2 (pin 10) controls amplifier 2. Driving either pin below 0.8V places its respective amplifier's output in high-impedance state and reduces its supply current to ≤40µA (at +5V). Floating or pulling ≥2.0V enables normal operation - enabling flexible power management without affecting the other channel.
Can MAX4133ESD drive heavy capacitive loads without oscillation?
Yes, MAX4133ESD is designed for stability with capacitive loads up to 160pF under unity-gain conditions. This specification is verified across temperature and supply voltage, eliminating the need for output isolation resistors when driving ADC input capacitance, long PCB traces, or piezoelectric sensors - a key advantage over many general-purpose op amps that require external compensation for such loads.
What package type and footprint does MAX4133ESD use?
MAX4133ESD is supplied in a 14-pin small-outline (SO) package conforming to JEDEC MS-012AC outline (5.0mm × 10.2mm body, 1.27mm lead pitch). Its land pattern matches standard SO-14 footprints; pins 1, 9, 11, 12, and 14 are no-connect (N.C.) and must remain unconnected on the PCB. This package enables high-density placement while supporting automated assembly and reflow soldering.
