Product details
Overview
MAX475EPD from Maxim Integrated is a quad, single-supply operational amplifier with rail-to-rail output swing, 10MHz unity-gain bandwidth, 15V/µs slew rate, and 2mA per amplifier supply current. It operates from +2.7V to +5.25V, guarantees ±50mV output swing to both rails, and features input voltage range extending to the negative rail - ideal for precision signal conditioning in battery-powered instrumentation.
For engineers reviewing the MAX475EPD datasheet, MAX475EPD pinout, MAX475EPD application, or MAX475EPD equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in portable equipment and servo-loops, and two confirmed industry alternatives for legacy design continuity.
Technical Context
The MAX475EPD integrates four independent bipolar op amps optimized for unity-gain stability and fast large-signal response. Its architecture supports rail-to-rail output swing (within ±50mV of VEE and VCC) and common-mode input range including the negative rail - enabling true single-supply operation without level-shifting circuitry.
Each amplifier delivers guaranteed 10MHz bandwidth and 15V/µs slew rate while consuming only 2mA per channel at +3V to +5V supply. Input bias currents flow out of both inputs, requiring matched source impedances to minimize offset error - a key layout consideration for high-accuracy applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +5.25V - enables direct interface with 3.3V and 5V logic systems without level translation. |
| Unity-Gain Bandwidth | 10MHz - supports stable closed-loop operation up to audio and low-RF frequencies with gain ≥1. |
| Slew Rate | 15V/µs min - ensures ≤700ns settling to 0.1% for 1V step, suitable for fast pulse amplification. |
| Output Swing | Within ±50mV of VEE and VCC - delivers full dynamic range across supply rails in single-supply configurations. |
| Input Common-Mode Range | Includes VEE (ground) - eliminates need for negative biasing in sensor front-ends and ADC drivers. |
| Supply Current per Amp | 2mA typical at +3V - balances speed and power for portable instrumentation with multi-channel requirements. |
| Input Offset Voltage | ±2.0mV max (0°C to +70°C), ±3.3mV max (–40°C to +85°C) - defines DC accuracy limit in precision gain stages. |
Pinout & Package
MAX475EPD is supplied in a 14-pin plastic DIP package (0.300" wide), RoHS-compliant and rated for –40°C to +85°C operation. Pin spacing conforms to JEDEC MS-001 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load; short-circuit protected; swings rail-to-rail. |
| 2 | INA− | Amplifier A inverting input - high-impedance node; bias current flows out; requires matched source impedance. |
| 3 | INA+ | Amplifier A noninverting input - same bias behavior as INA−; used for unity-gain buffer or noninverting gain stages. |
| 4 | VEE | Negative supply pin - connect to ground in single-supply mode; substrate tied to VEE. |
| 5 | VCC | Positive supply pin - bypass with 0.1µF ceramic capacitor close to pin for stability and PSRR. |
| 6 | INB+ | Amplifier B noninverting input - electrically identical to INA+; supports independent dual-channel configuration. |
| 7 | INB− | Amplifier B inverting input - matches INA− characteristics; bias current flows out. |
| 8 | OUTB | Amplifier B output - fully independent of OUTA; channel separation >120dB up to 300kHz. |
| 9 | INC− | Amplifier C inverting input - third channel input; same electrical specs as INA−/INB−. |
| 10 | INC+ | Amplifier C noninverting input - third channel input; supports parallel or cascaded signal paths. |
| 11 | OUTC | Amplifier C output - rail-to-rail swing; usable for multi-stage filtering or differential drive. |
| 12 | IND+ | Amplifier D noninverting input - fourth channel input; enables quad-channel signal processing on one IC. |
| 13 | IND− | Amplifier D inverting input - completes quad topology; bias current flows out like other inputs. |
| 14 | OUTD | Amplifier D output - final channel output; identical AC/DC performance to OUTA–OUTC. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad, single-supply op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | CMOS input (pA bias), lower supply current (600µA/amp), 6.4MHz GBW, ±150mV output swing at 3.3V | Better for ultra-low-power, high-impedance sensor nodes; insufficient slew rate (1.6V/µs) for fast servo feedback | Select when input bias <1pA and quiescent current <1mA/amp are mandatory; avoid where >10MHz bandwidth or >10V/µs slew is required. |
| AD8604ARUZ | RRIO, 8MHz GBW, 5V/µs slew, 1.2mA/amp, ±100µV offset, 0.25µV/√Hz noise | Superior DC precision and noise performance; lower bandwidth limits use in >5MHz signal chains | Prefer for high-resolution data acquisition where offset drift and noise dominate; not suitable for >5MHz transient response or >10V/µs slew demands. |
Compared with TLV2464IDR and AD8604ARUZ, MAX475EPD uniquely delivers 10MHz bandwidth and 15V/µs slew rate in a quad, rail-to-rail output, single-supply op amp - making it irreplaceable in legacy portable instrumentation requiring fast, full-rail signal handling without CMOS input limitations.

FAQ
What is the operating temperature range for MAX475EPD?
The MAX475EPD is specified for operation from –40°C to +85°C. This extended temperature grade (denoted by the "E" suffix) makes it suitable for industrial and automotive-adjacent environments where ambient conditions exceed commercial-grade limits. The device maintains its 10MHz bandwidth and 15V/µs slew rate across this full range, with input offset voltage increasing to ±3.3mV max at extremes.
Is MAX475EPD pin-compatible with other packages in the MAX475 family?
Yes - MAX475EPD uses the standard 14-pin DIP footprint shared by all MAX475 variants (e.g., MAX475CPD, MAX475ESD). Pin functions are identical across DIP, SO, and CERDIP packages. However, thermal resistance and maximum power dissipation differ: the plastic DIP package (MAX475EPD) has 10.00mW/°C derating above +70°C, limiting continuous operation at elevated ambient temperatures compared to SO or CERDIP versions.
Does MAX475EPD support dual-supply operation?
Yes - MAX475EPD operates from dual supplies of ±1.35V to ±2.625V, as confirmed in the Electrical Characteristics tables. In dual-supply mode, VEE connects to the negative rail (e.g., –2.5V) and VCC to the positive rail (e.g., +2.5V). Input common-mode range remains rail-inclusive, and output swing stays within ±50mV of each supply. Bypass capacitors must be placed from each supply to ground.
Can the input offset voltage of MAX475EPD be externally trimmed?
No - unlike the single-amplifier MAX473, the MAX475EPD (quad version) does not provide offset null pins. Its input offset voltage is factory-trimmed and fixed at ±2.0mV max over 0°C to +70°C, and ±3.3mV max over –40°C to +85°C. For applications requiring tighter DC accuracy, external calibration or post-processing compensation is necessary.
What is the recommended power supply bypassing for MAX475EPD?
A 0.1µF ceramic capacitor placed as close as possible between VCC and VEE pins is mandatory for stable operation. For improved high-frequency PSRR and channel separation (>120dB up to 300kHz), add a 10µF tantalum or aluminum electrolytic capacitor in parallel. Avoid long traces or vias between bypass caps and supply pins - layout directly impacts transient response and noise rejection.
