Product details
Overview
MAX408CSA-TG068 from Maxim Integrated is a single high-speed operational amplifier optimized for video-range signal amplification and fast data conversion systems. It delivers 100MHz gain bandwidth, 90V/µs slew rate, ±0.1% settling in 150ns, and drives 75Ω back-terminated transmission lines at 5VPP. It operates from ±4V supplies and supports input common-mode range within 1.5V of V+ and 0.5V of V−.
For engineers reviewing the MAX408CSA-TG068 datasheet, MAX408CSA-TG068 pinout, MAX408CSA-TG068 application, or MAX408CSA-TG068 equivalent, key selection criteria include settling time accuracy, capacitive load drive capability, offset voltage trimmability, and stability at gain ≥3 with internal compensation.
Technical Context
The MAX408CSA-TG068 uses internally compensated architecture requiring minimum closed-loop gain of 3 (non-inverting) to ensure ≥50° phase margin, even with 50pF capacitive load. Its open-loop gain is 10,000 V/V (80dB), and its dominant-pole response rolls off at 20dB/decade up to ~50MHz before an output-stage zero introduces peaking at 70–100MHz under specific RL/CL conditions.
It features trimmable input offset voltage via external resistors on pins 1 and 5, low 35nA input offset current, and differential input resistance of 3–10MΩ. The amplifier includes short-circuit protection and maintains >90dB inter-amplifier crosstalk isolation only in dual/quad variants - not applicable to the single MAX408CSA-TG068.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 100MHz - enables stable unity-gain-stable operation only at ACL ≥3; usable for 3× video gain at 30MHz |
| Slew Rate | 90V/µs - supports full-scale 5VPP transitions in <56ns, critical for pulse and waveform generation |
| Settling Time | 150ns to ±0.1% - ensures fidelity in 12-bit DAC buffer and ADC driver applications |
| Input Offset Voltage | 5–16mV - trimmable via external potentiometer on pins 1/5 to ≤±1mV for precision conditioning |
| Supply Voltage Range | ±4V to ±6V - compatible with legacy ±5V analog rails; not rated for 3.3V single-supply use |
| Output Drive | Drives 75Ω loads at 5VPP - directly interfaces with standard video distribution infrastructure |
| Common-Mode Input Range | Within 1.5V of V+, 0.5V of V− - accommodates wide-swing AC-coupled signals in test equipment front-ends |
Pinout & Package
MAX408CSA-TG068 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with JEDEC MS-012AC footprint. Thermal performance supports 471mW continuous dissipation at +70°C ambient with 5.88mW/°C derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (BALANCE) | Connects to external potentiometer wiper for trimming input offset voltage |
| 2 | Inverting Input (−IN) | Differential input node; high-impedance, 3–10MΩ input resistance |
| 3 | Non-Inverting Input (+IN) | Differential input node; referenced to same common-mode range as −IN |
| 4 | V− | Negative supply rail connection; must be decoupled with 0.1µF capacitor to ground |
| 5 | Offset Null (BALANCE) | Second terminal for external offset trim network; not signal-connected |
| 6 | Output (OUT) | Class-AB output stage capable of ±100mA short-circuit current and driving 150Ω loads |
| 7 | V+ | Positive supply rail connection; requires local 0.1µF bypass capacitor |
| 8 | NC | No internal connection; left unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated for ACL ≥3 | Eliminates need for external compensation components; guarantees ≥50° phase margin with 50pF load |
| Trimmable input offset voltage | Enables calibration to sub-millivolt level using external 10kΩ potentiometer across pins 1 and 5 |
| High output current drive | Delivers >100mA peak into short circuit; sustains 5VPP into 75Ω without clipping or distortion |
| Low input bias current | 650–1100nA typical - minimizes DC error in high-impedance sensor interface and transimpedance configurations |
| Short-circuit protected output | Withstands indefinite output-to-rail shorts without latch-up or permanent degradation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW, 940V/µs slew rate, but requires external compensation and has no offset null pins | Better for RF/IF gain stages; unsuitable where trimmable offset or guaranteed stability at G≥3 is required | Select LMH6629MA/NOPB only when bandwidth >500MHz is needed and layout allows careful compensation design |
| AD8001ARZ | 1.2GHz GBW, 2250V/µs slew, ±3.5V output swing on ±5V supplies, no offset null capability | Superior for ultra-high-speed ADC drivers; lacks pin-compatible offset adjustment for precision DC-coupled paths | Choose AD8001ARZ for >100MHz signal chains where offset drift tolerance exceeds ±2mV |
Compared with MAX408CSA-TG068, LMH6629MA/NOPB and AD8001ARZ offer higher bandwidth and slew rates but omit offset nulling and internal compensation for gain ≥3 - making them less suitable for video distribution, calibrated test gear, and legacy ±5V systems requiring guaranteed stability without tuning.

FAQ
Is MAX408CSA-TG068 still in production?
No - MAX408CSA-TG068 is Not Recommended for New Designs due to discontinuation of its wafer fabrication process. It remains available through authorized distributors and Aetrix Electronics for legacy system repair and continuity programs, with full datasheet and application support retained for existing users.
What is the function of pins 1 and 5 on MAX408CSA-TG068?
Pins 1 and 5 on MAX408CSA-TG068 are dedicated offset null terminals. They connect to opposite ends of a 10kΩ potentiometer (wiper to V−), enabling precise trimming of input offset voltage to ≤±1mV. These pins carry no signal current and do not affect AC performance or bandwidth of the MAX408CSA-TG068.
Can MAX408CSA-TG068 operate at gain = 1?
No - MAX408CSA-TG068 is internally compensated for minimum closed-loop gain of 3 (non-inverting) or –2 (inverting). Attempting unity-gain configuration causes instability, oscillation, or excessive peaking due to insufficient phase margin. For G = 1 applications, consider externally compensated alternatives like AD8055 or THS3091.
Does MAX408CSA-TG068 support single-supply operation?
No - MAX408CSA-TG068 is specified only for dual-supply operation from ±4V to ±6V. Its input common-mode range extends to within 1.5V of V+ and 0.5V of V−, and output swing is asymmetric around ground. It lacks rail-to-rail input/output capability and is not characterized for 3.3V or 5V single-supply use.
What is the maximum capacitive load MAX408CSA-TG068 can drive stably?
MAX408CSA-TG068 maintains ≥50° phase margin with up to 50pF capacitive load when configured for ACL ≥3 and powered from ±5V. Driving >50pF (e.g., long PCB traces or cables) requires external isolation resistor (e.g., 10–50Ω in series with output) to prevent peaking or ringing, as confirmed in Figure 4 of the MAX408CSA-TG068 datasheet.
