Product details
Overview
MAX6198BESA-TG069 from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 4.096V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent current - ideal for high-accuracy ADC/DAC biasing in battery-powered handheld instruments.
For engineers reviewing the MAX6198BESA-TG069 datasheet, MAX6198BESA-TG069 pinout, MAX6198BESA-TG069 application, or MAX6198BESA-TG069 equivalent, this page provides verified specifications, SO-8 package details, load-regulation behavior at 500µA, dropout performance (100–200mV), and real-world use cases in precision 3V/5V systems and industrial process control.
Technical Context
The MAX6198BESA-TG069 employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy across –40°C to +85°C. It operates as a series-mode reference capable of sourcing and sinking up to ±500µA while maintaining stability with capacitive loads from 0 to 2.2nF.
Its supply current remains virtually immune to input voltage variation (0.8µA/V change over VIN = VOUT + 0.2V to 12.6V), and it features internal compensation for fast settling (160µs to 0.1%) without requiring external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±2mV - tightly specified for 12-bit DAC/ADC full-scale calibration and ratiometric sensor excitation. |
| Temp Coefficient | ≤5ppm/°C - ensures ≤±0.21mV drift over –40°C to +85°C, critical for uncalibrated field instrumentation. |
| Quiescent Current | ≤35µA - enables multi-year operation on coin-cell batteries in portable data loggers. |
| Dropout Voltage | 100–200mV at 500µA load - supports regulation from 4.3V rails in 4.5V nominal systems. |
| Load Regulation | 0.15µV/µA - delivers <75µV shift across full 500µA load range, preserving LSB integrity in 16-bit converters. |
| Line Regulation | 25µV/V - maintains output stability despite ±100mV input ripple common in switching regulator outputs. |
| Capacitive Load Stability | 0–2.2nF - eliminates need for output capacitor in space-constrained PCB layouts. |
Pinout & Package
MAX6198BESA-TG069 is housed in an 8-pin SO (Small Outline) package per outline 21-0041, RoHS-compliant with lead-free finish. Pin 1 is OUT, Pin 2 is IN, Pin 4 is GND; Pins 1, 3, 5, 7, and 8 are No Connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection - must remain unconnected; floating or tied to GND has no effect on operation. |
| 2 | IN | Supply input - accepts 4.296V to 12.6V; minimum headroom is VOUT + 0.2V for regulation. |
| 4 | GND | Analog ground reference - requires low-impedance connection to system AGND plane. |
| 6 | OUT | Precision 4.096V reference output - capable of sourcing/sinking ±500µA with <200mV dropout. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enable ±2mV initial accuracy and <5ppm/°C tempco without external calibration. |
| Curvature-correction circuit | Compensates second-order bandgap nonlinearity, reducing thermal drift error by >50% vs. standard references. |
| Internal compensation | Guarantees stability with 0–2.2nF capacitive loads - no external compensation required. |
| Low-noise architecture | Delivers 100µVP-P (0.1Hz–10Hz) noise - suitable for 16-bit SAR and sigma-delta ADC reference inputs. |
| Fast turn-on settling | Reaches 0.1% of final value in 160µs - supports low-duty-cycle power-gating in portable meters. |
Applications
| Hand-Held Instruments | Analog-to-Digital Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6198AESA+ | ±1mV initial accuracy (tighter), same 4.096V output and SO-8 package | Better suited for 18-bit+ metrology-grade systems where <1mV error budget is mandatory | Select MAX6198AESA+ when initial accuracy is prioritized over cost; MAX6198BESA-TG069 offers optimal balance for 16-bit applications. |
| REF5040AIDR | 4.096V output, ±0.5mV initial accuracy, 3ppm/°C max tempco, but 95µA quiescent current and SO-8 package | Higher power consumption limits use in ultra-low-power battery devices; superior long-term stability (15ppm/1000hrs) | Choose REF5040AIDR only when long-term drift is the dominant concern and supply current >35µA is acceptable. |
Compared with MAX6198AESA+, MAX6198BESA-TG069 trades 1mV initial accuracy for lower cost and identical thermal performance; versus REF5040AIDR, it delivers 2.7× lower quiescent current at the expense of slightly higher long-term drift - making it the preferred choice for portable, battery-operated precision measurement.

FAQ
What is the output voltage tolerance of MAX6198BESA-TG069 over temperature?
The MAX6198BESA-TG069 guarantees ±2mV initial accuracy at +25°C and a maximum temperature coefficient of 5ppm/°C. Over the full –40°C to +85°C operating range, total output variation is bounded by ±2mV plus ±0.21mV (5ppm/°C × 4.096V × 125°C), resulting in a worst-case tolerance of ±2.21mV - confirmed in the Electrical Characteristics table for MAX6198B under "Output Voltage".
Can MAX6198BESA-TG069 drive a 1000pF capacitive load?
Yes, MAX6198BESA-TG069 is stable with capacitive loads from 0 to 2.2nF, as explicitly stated in the Capacitive-Load Stability Range specification. A 1000pF (1nF) load falls well within this range and requires no series resistor or external compensation - enabling direct connection to ADC input capacitors or filtering networks without risk of oscillation.
What is the minimum input voltage required for regulation with MAX6198BESA-TG069 at 500µA load?
The minimum input voltage is defined by the dropout specification: 100–200mV above the nominal 4.096V output. At 500µA load, MAX6198BESA-TG069 requires VIN ≥ 4.196V (typical) to 4.296V (max) to maintain regulation - consistent with the "Dropout Voltage (Note 4)" row in the MAX6198 Electrical Characteristics table.
Does MAX6198BESA-TG069 support both sourcing and sinking current?
Yes, MAX6198BESA-TG069 is fully bidirectional: it can source 0 to +500µA and sink –500µA to 0, as confirmed in the "Sourcing" and "Sinking" test conditions across all MAX6190-family electrical tables. This capability enables use in active filter biasing, programmable gain amplifier references, and bipolar DAC configurations.
Is MAX6198BESA-TG069 RoHS-compliant and lead-free?
Yes, MAX6198BESA-TG069 uses a lead(Pb)-free / RoHS-compliant package, indicated by the "+" suffix in the ordering information (e.g., MAX6198BESA+). The datasheet explicitly states "+Denotes a lead(Pb)-free /RoHS-compliant package", and the device meets JEDEC J-STD-020 moisture sensitivity level 1 requirements.
