Product details
Overview
M61538FP#DF0G from Renesas Electronics is a 6-channel electronic volume IC controlled via 2-wire serial interface, delivering independent attenuation per channel from 0 dB to –95 dB in 1 dB steps. It supports ±7 V analog supplies or +10 V single supply, features 0.85 µVrms output noise (typ.), and targets multi-channel audio signal routing in home AV systems.
For engineers reviewing the M61538FP#DF0G datasheet, M61538FP#DF0G pinout, M61538FP#DF0G application, or M61538FP#DF0G equivalent, key selection criteria include its six independent analog volume channels, IHF-A weighted noise performance, dual-supply/single-supply flexibility, and compatibility with microcontroller-based audio control systems.
Technical Context
The M61538FP#DF0G implements six independent 25 kΩ digitally controlled analog attenuators, each with 64-step resolution (0 to –95 dB + mute). Its 2-wire serial interface uses separate CLOCK and DATA lines with latch-on-falling-edge timing, supporting three data formats for grouped channel programming (L/R, C/SW, SL/SR).
It integrates internal power-on reset that blocks serial input until DVDD reaches 2.6 V, and supports two operating modes: ±4.5–7.5 V analog rails with +2.7–5.5 V digital supply, or +9–12 V single analog rail with +4.5–5.5 V digital supply - all with strict sequencing requirements (VEE ≤ DGND < DVDD ≤ VCC).

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12, 14, 16, 21, 23 | AGND | Analog ground reference for all six channels; multiple pins reduce ground impedance and channel crosstalk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-channel electronic volume applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4187VT | 8-channel, I²C interface, lower max supply (±6.5 V), higher THD (0.002% typ.) | Targets professional audio gear requiring more channels and tighter I²C timing compliance | Select AK4187VT when expanding beyond 6 channels or requiring I²C instead of custom 2-wire protocol |
| PGA2311UA | 2-channel, SPI interface, ±15 V supply capable, higher noise (2.1 µVrms), no mute function | Used in high-voltage studio preamps where wide dynamic range outweighs channel count | Select PGA2311UA for dual-channel, high-supply, low-distortion applications where SPI control is preferred |
Compared with AK4187VT and PGA2311UA, the M61538FP#DF0G uniquely balances 6-channel independence, ultra-low noise (0.85 µVrms), and dual-supply flexibility in a cost-optimized SSOP24 package - making it optimal for mainstream home AV volume control where channel count, noise, and supply versatility are primary constraints.

FAQ
What is the maximum allowable analog supply voltage for M61538FP#DF0G?
The M61538FP#DF0G supports two configurations: ±4.5 V to ±7.5 V analog supplies (VCC–VEE ≤ 16 V), or +9 V to +12 V single analog supply. Exceeding these ranges risks permanent damage. The absolute maximum VCC–VEE rating is 16 V, and VEE must always be ≤ DGND < DVDD ≤ VCC per the datasheet's note 1.
Does M61538FP#DF0G support I²C communication?
No, the M61538FP#DF0G does not support standard I²C. It uses a proprietary 2-wire serial interface with separate CLOCK and DATA lines, where data is latched on the falling edge of CLOCK. It lacks I²C addressing, ACK/NACK, or START/STOP protocols - requiring custom MCU firmware for timing compliance (tSHD/tSLD ≥1.6 µs).
What is the function of the AGND pins on M61538FP#DF0G?
The M61538FP#DF0G has seven AGND pins (1, 12, 14, 16, 21, 23, and additional AGND connections shown in block diagram) to provide low-impedance, low-noise return paths for all six analog channels. This multi-pin grounding strategy minimizes ground bounce and inter-channel crosstalk, directly supporting the –110 dB typical cross talk specification.
Can M61538FP#DF0G operate with only a single +5 V supply?
No, the M61538FP#DF0G cannot operate with only +5 V. It requires either dual analog supplies (e.g., +7 V / –7 V) or a higher single analog supply (+9–12 V), plus a separate +2.7–5.5 V digital supply (DVDD). The +5 V rail alone is insufficient for analog signal handling; using it exclusively would violate absolute maximum ratings and cause functional failure.
What does the "#DF0G" suffix indicate in M61538FP#DF0G?
The "#DF0G" suffix denotes the specific tape-and-reel packaging and environmental compliance variant of the M61538FP: "DF" indicates tube-to-tape conversion per Renesas standard, "0" specifies RoHS-compliant lead finish (Pb-free), and "G" confirms green (halogen-free) molding compound - fully compliant with EU RoHS Directive 2011/65/EU.
