Product details
Overview
BUF602IDBVTG4 from Texas Instruments is a high-speed closed-loop buffer IC designed for AC-coupled, single-supply signal conditioning in wideband analog systems. It delivers 1000MHz bandwidth (±5V), 8000V/µs slew rate, ±60mA continuous output current, and integrated mid-supply reference (2.5V @ ±5V supply) - enabling low-component-count video, clock, and instrumentation signal buffering.
For engineers reviewing the BUF602IDBVTG4 datasheet, BUF602IDBVTG4 pinout, BUF602IDBVTG4 application, or BUF602IDBVTG4 equivalent, key selection criteria include its SOT23-5 package footprint, self-referenced AC-coupling capability, 0.1dB flatness to 240MHz, differential gain/phase performance (0.15%/0.04°), and compatibility with 50Ω transmission line driving.
Technical Context
The BUF602IDBVTG4 implements a fixed-gain x1 closed-loop architecture with internal 50kΩ resistive divider generating VREF at VS/2. Its output stage supports both sourcing and sinking up to ±350mA peak into capacitive or resistive loads while maintaining <2Ω output impedance below 20MHz.
It operates across dual supplies (±1.4V to ±6.3V) or single supplies (+2.8V to +12.6V), with quiescent current as low as 3.9mA at +5V. The mid-supply reference buffer provides 200Ω output impedance, 800µA sourcing / 70µA sinking capability, and is specified for DC–250MHz operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DR | Higher 1.8GHz bandwidth but no integrated VREF; requires external bias network for AC coupling | Better suited for DC-coupled RF IF stages; less optimal for cost-sensitive video line drivers | Select when >1GHz bandwidth is mandatory and external bias design overhead is acceptable |
| LMH6702MF | Lower 1.6GHz bandwidth, higher 12mA quiescent current, no VREF output; SO-8 only | Preferred for legacy SO-8 layouts; lacks self-biasing capability for compact SOT23-5 designs | Select when board space allows SO-8 and mid-supply reference is implemented externally |
Compared with THS3201DR and LMH6702MF, the BUF602IDBVTG4 uniquely integrates a low-impedance mid-supply reference in a 5-pin SOT23 package, reducing component count and PCB area while maintaining 1000MHz bandwidth and 0.1dB flatness - critical for space-constrained video and instrumentation designs.

FAQ
What is the maximum operating voltage for BUF602IDBVTG4 in single-supply mode?
The BUF602IDBVTG4 supports a maximum single-supply operating voltage of +12.6V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. At +12.6V, the device maintains full functionality including 2.5V mid-supply reference generation and ±60mA output drive, making it suitable for high-voltage analog front-ends in industrial test gear.
Does BUF602IDBVTG4 require external compensation components?
No, the BUF602IDBVTG4 is internally compensated and does not require external compensation components. Its closed-loop x1 architecture is stable into capacitive loads up to 100pF (with ≤0.5dB peaking), as verified in Figure 17 of the SBOS339B datasheet. For loads >100pF, a series 20Ω resistor at the output is recommended to maintain stability - a design guideline explicitly provided in the Application Information section.
Can BUF602IDBVTG4 be used with a +3.3V supply?
Yes, the BUF602IDBVTG4 is fully specified for +3.3V single-supply operation. At +3.3V, it delivers 600MHz bandwidth (VO = 500mVPP), 800V/µs slew rate, and a 1.65V mid-supply reference (±0.07V). Output swing is +2.3V / +1.0V (RL = 500Ω), and quiescent current is 5.0mA typical - confirming robust functionality across the entire +2.8V to +12.6V range.
What is the thermal resistance (θJA) of BUF602IDBVTG4 in its SOT23-5 package?
The thermal resistance θJA of BUF602IDBVTG4 in the SOT23-5 (DBV) package is 150°C/W, as stated in the Thermal Characteristics table. This value assumes standard JEDEC 2-layer board conditions. With a maximum junction temperature of +150°C and ambient up to +85°C, the device can dissipate up to 433mW continuously under typical PCB layout - sufficient for most 50Ω line-driving applications without heatsinking.
How does the VREF pin function in AC-coupled configurations?
In AC-coupled configurations, the VREF pin of BUF602IDBVTG4 provides a low-impedance (200Ω), buffered midpoint voltage (e.g., 2.5V at +5V supply) that biases the IN pin via an external coupling capacitor. This eliminates the need for external resistive dividers. The VREF output sources up to 800µA and sinks 70µA, supporting direct connection to the input capacitor without droop - a key enabler for compact, high-density video and clock distribution designs.
