Product details
Overview
TS464CD from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for low-voltage audio signal conditioning in portable equipment. It operates from 2.7 V to 10 V, delivers ±2.4 V output swing at ±2.5 V supply, exhibits 4 nV/√Hz input noise and 0.003 % THD at 1 kHz - enabling high-fidelity microphone pre-amplification and line-level audio buffering in CD players and sound cards.
For engineers reviewing the TS464CD datasheet, TS464CD pinout, TS464CD application, or TS464CD equivalent, key selection criteria include its SO-14 package footprint, quad-channel rail-to-rail output drive, low-noise performance below 5 nV/√Hz, and guaranteed operation down to 2.7 V single-supply - critical for battery-powered multimedia interfaces and analog front-end design.
Technical Context
The TS464CD integrates four independent op-amps sharing a common SO-14 package with fully rail-to-rail output stage capable of swinging within 100 mV of each supply rail under 2 kΩ load. Its input stage supports common-mode voltage range from VDD +1.15 V to VCC −1.15 V, enabling direct interfacing with ADCs and DACs operating near supply rails.
Each amplifier features 12 MHz gain-bandwidth product (typ.), 4 V/µs slew rate (typ.), and 85 dB common-mode rejection ratio - ensuring stable unity-gain buffer operation and accurate differential signal amplification in multi-channel audio paths without phase distortion or clipping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower supply range (2.7–6 V), higher input offset (2 mV typ.), 6.4 MHz GBW, 1.6 V/µs slew rate. | Optimized for low-power sensor signal conditioning, not audio playback; lacks THD spec below 0.01 %. | Select when power budget <1.5 mA/channel is mandatory and audio fidelity is secondary to battery life. |
| LMV324DR | Non-rail-to-rail output (swing limited to VCC−1.5 V), higher noise (30 nV/√Hz), 1 MHz GBW, 1 V/µs slew rate. | Targeted at cost-sensitive industrial monitoring, not audio; cannot deliver full swing into 3.3 V line drivers. | Choose only for DC-coupled control loops or slow-signal buffering where audio bandwidth and swing are irrelevant. |
Compared with TLV2464IDR and LMV324DR, TS464CD uniquely combines rail-to-rail output swing, sub-5 nV/√Hz noise, and 0.003 % THD in a quad SO-14 package - making it the sole option among these three for high-SNR, wide-dynamic-range audio signal chains requiring simultaneous multi-channel fidelity.

FAQ
What is the maximum junction temperature rating for TS464CD?
The absolute maximum junction temperature for TS464CD is 150 °C, as specified in Table 1 of the DS1416 Rev 4 datasheet. Thermal resistance junction-to-ambient (RthJA) for the SO-14 package is 103 °C/W, meaning at 2.8 mA per amplifier (11.2 mA total) and 25 °C ambient, junction temperature rise is approximately 1.15 °C - well within safe operating limits.
Does TS464CD support single-supply operation with ground-referenced inputs?
Yes. TS464CD supports true single-supply operation: its common-mode input voltage range extends from VDD +1.15 V to VCC −1.15 V. With VDD = 0 V and VCC = 5 V, inputs operate from +1.15 V to +3.85 V - allowing use with AC-coupled or DC-biased signals referenced to mid-supply, provided input sources comply with this range.
Is the TS464CD pinout compatible with other quad op-amps in SO-14 packages?
No. TS464CD uses a proprietary pinout: Pin 4 = VDD (negative rail), Pin 8 = VCC (positive rail), and channels are arranged sequentially (Amp 1–4). It is not pin-compatible with industry-standard quad op-amps like LM324 or TL074, which place power pins at Pins 4 and 11 or 4 and 8 with different channel ordering.
What is the minimum load impedance TS464CD can drive while maintaining rail-to-rail output swing?
TS464CD maintains ±2.4 V output swing into 2 kΩ loads at ±2.5 V supply, as tested per Table 3. Driving lower impedances (e.g., 600 Ω) causes output swing compression and increased THD; for headphone loads, external current-boosting stages or dedicated headphone amplifiers are recommended per ST application note AN2817.
